After dropping off the groceries at their respective homes, Sheldon and Amy drove to the Lego store at the Glendale Galleria, as they had every Saturday for the past ten weeks.

The employees had become quite familiar with the pair's habits. Every week they would ask if they could be of assistance, even though the answer was always, "We're just looking." However, this time Sheldon surprised them all, including Amy.

"I would like to purchase the Ghostbusters firehouse headquarters," he announced.

The salesperson set one aside while they continued browsing.

"I've contemplated buying that set for weeks," he confessed to Amy. "Leonard's going to be so jealous."

Next they headed for the build your own minifigure station. As per tradition, they attempted to outdo each other by seeing who could come up with the most unique combinations.

Sheldon surprised Amy again. He selected three of her creations and placed them in a minifigure 3-pack bubble.

"I'd like to buy these for myself, if you don't mind. Feel free to choose three of mine if you wish. My treat."

Amy examined the multiple figures Sheldon created. He had really let his imagination run wild with some of them, but two in particular caught her eye. Standing off to one side was a figure wearing a skirt with long dark hair and glasses holding a microscope. Next to it was a figure with short dark hair wearing a red shirt and holding a comic book. She selected the two then chose one of the more wild creations to complete her pack.

Back at the car, their purchases stowed in the backseat, Amy was about to buckle her seatbelt when Sheldon placed his hand on her arm. "I could use some help putting the Ghostbusters set together. Are you free tonight?"

She hesitated.

"I know it's not part of the contract. I'm sorry for suggesting it."

"It's not that. That actually sounds fun, but tonight's my only chance to do laundry before I return to work on Monday."

"Why don't you bring your laundry to my place? I'm the only person who ever uses the machines on Saturday night. We'll have the whole laundry room to ourselves."

"Okay," she consented.

"Leonard and Penny are going out with the Wolowitz's for dinner, so we'll also have free rein of the apartment."

She gave him a shy smile. "I look forward to it."

They stopped at her apartment where she made them a quick lunch of grilled cheese sandwiches and canned tomato soup, then gathered her laundry and headed to Sheldon's.

"Would you like a cup of tea before we get started?"

Amy joined him at the island. "I'll have a lemon zinger, please.

"Excellent choice. I will have one as well."

"So, what are your plans for my minifigure creations?" She asked as they waited for the water to boil.

He extracted the figures from their packaging and placed them on his desk next to his Golum figure. "Now I'll be able to look at them whenever I'm at my computer. What do you plan to do with mine?"

"I think I'll display them on my nightstand so they're the last thing I see before I go to bed and the first thing I see when I wake up."

After tea, they cleared off the coffee table to make way for their project. Sheldon slit the box open carefully with a utility knife. He pulled each numbered bag of pieces out one by one and sorted the numbers in piles then examined the instruction booklet.

Amy picked up a bag with a '2' on it. "I see a minifigure in here!"

Sheldon gently grabbed her wrist. "Woah, woah, woah. We can't just go opening packages willy nilly. We need to follow the directions. The first thing we need to do is put together the foundation. Can you pass me the large base plate?"

She reluctantly set the bag down and reached for the base plate. She handed it to Sheldon then located the next piece. They worked together for the next 30 minutes to complete the foundation of the firehouse.

"This is really fun. I've never put together a Lego set before."

"Never?! I've completed many sets over the years. I'd show them to you if they weren't in storage."

At 8:15 he collected his soiled clothing then led the way to the laundry room.

"In my haste to ensure I had all my laundry, I forgot to bring any detergent," she admitted.

"Not to worry. I have more than enough for the two of us."

Sheldon carefully measured the liquid and poured it into Amy's machine then did the same with his own.

Back in the apartment, he set the timer on his watch to remind them when to check on their clothes then resumed reading the Lego instructions. They set to work again until the timer went off, signaling the end of the wash cycle.

"I think we're off to a good start," he said on the way back from the laundry room.

"This is the most fun I've had on a Saturday night in a long time. Maybe even ever."

"Me too. I'd much rather build Legos with you than Leonard."

They took their seats once more while Sheldon set the timer again.

Amy twirled the Winston Zeddemore figure between her thumb and index finger. "I have to ask. Out of all the Lego sets we saw at the store, what made you choose this one?"

"The original Ghostbusters movie from 1984 is one of my all-time favorites. I've watched it 11 times - 5 times on VHS, 4 times on DVD, and twice on Blu-ray."

"I saw it once, and that was years ago. I don't remember much about it."

Sheldon's jaw dropped. "Seriously? Before we go any further, you should watch it again so you can appreciate this more."

He went to the kitchen and removed a popcorn popper.

She followed him over to the island. "Wait, we're actually doing this right now?"

"Yes. You'll appreciate our efforts more when you know who all the characters are."

They settled back on the couch side by side with a huge bowl of popcorn in front of them. Halfway through the movie, the timer rang.

Sheldon sighed. "I'm beginning to wish we had waited to start the movie after the laundry was done."

He excused himself to retrieve his shirt folding board.

"I've never tried one of those. Do they really work?"

He extracted his clothes from the dryer. "Watch this!"

She observed as he centered a t-shirt on the board and expertly flipped the panels until it was perfectly folded.

"That's amazing! Can I try it?"

"Of course."

She lay one of her blouses on it then looked at him questioningly. "What do I do first?"

"First you'll fold the bottom of your blouse up until it's even with the bottom of the board."

She followed his direction then flipped the right panel while he made a disapproving sound.

"What's wrong?"

"The left panel should be folded first. Let me help." He stood behind her then placed his hands on hers as he guided them to flip each panel in the correct order.

They folded two more shirts together, then he stood next to her and watched her fold two more. "You're getting better. Don't worry about speed yet. That will come once you have the technique down."

"I feel like I'm holding you up. I think I'll go back to the old-fashioned way so you can finish your shirts."

Sheldon quickly folded his remaining shirts then folded his socks as well. He looked over at his companion sorting through her clothing pile. "Amy, I don't remember ever seeing you wear anything in leopard print before, and I remember everything."

She quickly shoved the item in question under a cardigan. "That's because you haven't."

"Why are you hiding it?"

"The same reason you were appalled when I saw your underwear."

Sheldon stammered, "Oh. I... I thought maybe it was a shirt or something."

They both looked away and focused their eyes on their own tasks. When all the neatly folded clothing was placed in their laundry baskets, with the unmentionables tucked out of view, they silently climbed the stairs up to 4A.

They returned to their respective spots on the couch, avoiding eye contact. Sheldon resumed play on the movie. Ten minutes later, Amy gingerly rested her head on his shoulder. When he didn't pull away, she snuggled closer to him, and he placed his arm around her shoulders. They sat quietly through the rest of the movie.

As the credits rolled, she finally looked at him. "Sheldon, remember earlier when you said coming over tonight wasn't part of our contract and you were sorry for suggesting it?"

"Of course I do. I remember everything. I remember what I ate for lunch on May 24, 2010..."

She lay her hand on his arm. "That was bad wording on my part. What I meant to say was we don't need a contract to tell us to spend time together."

"Really?"

"Really. What gave you the impression that I wouldn't come here if I wasn't obligated?"

He looked down at his lap. "I was worried that you were just humoring me."

"Sheldon, look at me. When you first showed me the contract and I read that my obligation would last 12 weeks, I was flabbergasted. I thought after a few days of chauffeuring you around was more than sufficient."

Had it been anyone else who presented me with those terms, I never would have signed, but I did because I really like you. You've become an integral part of my life. When my obligation has been fulfilled, I'm not going anywhere."

"I really like you, too."

They smiled at each other then started cleaning up.

"We still have a lot of work left on this set. Are you free again next Saturday?" He asked.

"I am."

"Good. I'll hide this in my room so Leonard doesn't find it and play with it."

A hour after Amy left, the Hofstadters returned home.

"You're home kind of late," Sheldon accused them.

"Sorry, if we worried you, Sheldon," Leonard apologized. "We played some couples games then got to talking about married life."

"When Bernadette brought out their wedding album, it made us realize just how rushed our wedding was. We have the online video of our ceremony but no pictures, and our friends and families weren't there," Penny said wistfully.

"So we decided to get married again," Leonard finished.

Sheldon furrowed his brow. "Get married again? How is that possible?"

"We'll renew our vows and have a small reception for close friends and family. We're thinking of doing it two weeks from today on the rooftop," Penny explained. "Leonard's mother will be in town, and my brother just got out of prison due to overcrowding, so the timing is perfect. Make sure you invite Amy."

"Of course I'll invite Amy. It's in our contract that she accompany me to events."

Penny winked at him. "Yeah, because that's the only reason."
