"I don't understand," Amy admits.

"I suppose that is what the problem is. I don't understand either."

"Then what are you trying to do here? Are you trying to confuse me more?"

"I am trying to understand," he explains.

"Understand what?"

"Penny, may have also mentioned some horse manure about the importance of physical contact in a relationship."

"Really?"

"I usually wouldn't talk to her about such things, but I was desperate."

"Obviously. Sheldon, I think that you should leave."

"I don't want to."

"You are not comfortable. That is okay."

"Are you sure?"

"It is apparent to me that this just is not going to work out. We can't force something to work just because we want it to. It is like an experiment, you know? Just because you want your hypothesis to be right, doesn't mean that it is."

"My hypotheses are usually right."

"I think that you're going to have to accept that this one is wrong."

"I am not willing to do that," he argues.

"Why not?"

He doesn't say anything. He kisses her again, this time far less awkwardly. Amy still can't make sense of his actions. She isn't sure if it is because of his out of character behavior, or the fact that she already drank a bottle of wine before his arrival. Sheldon feels something abnormal at the pit of his stomach as he kisses Amy. She asks himself if it is the kiss, or whatever 'serum of courage' Penny fed to him earlier.

Sheldon sits on Penny's couch, as she stands at the stovetop.

"Penny, I have come to a conclusion."

"What's that?"

"You are right."

"I think that we should mark that down on the calendar, as the day you finally admitted that I am right about something. I am telling you, if you want to keep Amy you have to sleep with her."

He shakes his head, "I am not going to go quite that far. I think that what you said about physical contact has some truth to it. Some people need to have physical contact in order for them to feel affection."

"So you are going to sleep with her?"

"No! I am not going to engage in coitus as a means of winning her back."

"So what is your plan, Romeo?"

"Romeo? That is a terrible thing to call me. My preference of ending for this does not involve my untimely death, or Amy's for that matter."

Penny giggles, "What is your plan Sheldon?"

"I will get a nice bottle of wine, and apologize. I will beg her to take me back."

"Let me know how that works out for you."

"You don't think that will be enough?"

"Where does the physical contact come into play, in this scenario?"

"I'll hold her hand," he suggests.

"I don't think that is going to do it," Penny insists.

"What if I give her a long, passionate kiss?"

"Yeah, that will happen."

"Do you have any other suggestions?"

"Yes, drink this," she hands him a beverage.

"What is it?"

"It is courage serum."

"What's in it?"

"Try it, and see."

"I have tasted your cooking," he points out.

"It is just jell-o, Sheldon."

"Strawberry?"

"Of course."

He drinks the concoction, "Delightful, can I have another?"

She hands him two more, "See, even I can make jell-o."

He reaches for a second glass, "What is your secret? It has an extra kick to it."

She grins, "I mixed in some love."

"No, really, what is your secret?"

"Extra sugar," she fibs.

"I do like to live dangerously."

Amy decides to test Sheldon's limits. She pushes his jacket off him, and onto the floor. He moves his hand. He cradles her face as he kisses her. He feels fire rise from his chest up his neck as her fingers touch his neck. Before he knows it he is standing in the doorway of her bedroom, shirtless. He kicks off his shoes, and she leads him into her room. They move closer to her bed. He gently removes her glasses, and places them on her bedside stand.

Hours later he awakens in a puddle of drool. The air from the ceiling fan hits his barefoot. His foot sticks out from under the sheet. He opens his eyes, and tries to orient himself. His head is pounding. He lays on his side, staring at a wall that does not belong in his room. He rolls onto his side, and much to his chagrin he finds Amy lying next to him. He realizes he is in her bed. An internal dialogue of panic begins. He quietly rolls away from her, and slips out of the bed. He hurriedly collects his belongings. He can't find his right sock. He exits the room, and decides to chalk the sock up to a loss. He quickly gets dressed, and exits the apartment. Once he's on the street he pulls his phone out of his pocket.

"Hello?" A sheepish voice answers him from the other end.

"I need you to come get me. Now!"

"Sheldon, where are you?"

"I am in front of Amy's building."

"Okay, I'll be there in a few."

Exactly seven minutes later Penny pulls up to the curb. Sheldon gets into the passenger's seat.

"You okay?"

Sheldon doesn't answer. She puts the car into gear, and drives away. The ride back is nearly silent. They stop at a red light, and she notices that he is missing a sock.

"What happened to your sock?"

"We engaged in coitus," he answers.

Penny starts laughing hysterically, "You call me at six thirty on a Saturday morning, to pick you up from Amy's apartment, because you engaged in coitus? That is the funniest thing that you have ever said," she informs him, as they pull into a parking spot.
