A/N : Thanks to Knightlark and That Creative One for the ideas for this chapter and thanks to all who reviewed. I always need more ideas for pranks and I still don't own the Avengers or any of the characters.

Day 8

Tony paced the room with anger in every step. That last revenge prank was SO not cool. He needed to think up a way to get back at her without her knowing. What to do, what to do? The idea hit him as hard and as suddenly as a ton of bricks. She always knew his plans when he had smaller pranks, so what if he distracted her and set up a big prank. Something she could never guess or see coming. Yes, that was definitely the way to go.

He looked up a smaller prank on Google to use the next day, while thinking up something bigger to use sometime in the near future.

That night, Tony snuck out late to run to the store and buy some Coke and mint mentos. It was one of the simplest tricks to play assuming he could get Natasha to drink a glass of Coke. She was known to drink one if offered, but rarely drank it otherwise.

Tony grabbed an ice tray and filled it up before dropping a mento into each hole. He stuck it in the freezer and went to bed, still trying to figure out the big prank he planned to play.

In the morning, Tony got up, went through his morning routine, and went to the kitchen, where Natasha was already up and drinking a cup of coffee while Clint made her breakfast. Tony put together a normal glass of Coke for himself and called out "Hey, Natasha, want a glass of Coke? I picked some up last night while I was out."

"Sure."

Tony smiled slightly and got out the mentos tray of ice cubes. Clint sighed from beside the stove. "It's not going to work."

Tony smirked. "It's not supposed to."

Clint looked surprised at this, but Tony offered no more information. He figured out his big prank the night before and it was just a matter of time before Natasha would be in deep sewer. Literally. Tony was working on rigging a pipe in the kitchen to blow when she was nearby and BOOM, she would be covered in sewage. She would probably kill him before he got a chance to make it to his suit, but he needed to be able to prank her. Just once and he could carry on with his life.

Tony brought the drink out and set in front of Natasha and taking a seat a few chairs down from her. He turned his head a moment to take a peek at the TV and heard a clink of ice cubes. He turned back and Natasha was taking a sip from the Coke glass and it didn't look like she had switched his cup. It was in the exact same place as before.

Tony shrugged and took a sip of his own glass. Clint came out a minute later and set a plate of eggs and bacon in front of both Natasha and Tony. When Tony raised an eyebrow at this, Clint simply replied "You're going to need it if you keep up with what you're doing."

Natasha pretended to be oblivious, but they all knew that she knew what was going on. Tony was taking another gulp of his soda when, out of nowhere, fizz exploded from the glass and soaked his pants. Clint chuckled, Natasha smirked, and Tony frowned down at his soaked pants. As he got up to go change, Steve entered the room and laughed. "Have an accident?"

Tony bit back a comment about Steve's suit and shoved his way past him. Thor was next to see him and looked confused. "Man of Iron, why are your pants covered in a liquid."

Tony frowned more and said "Not a word."

Thor shrugged, knowing that someone else would tell him and sauntered off. As Tony pulled on a new pair of pink skinny jeans (he made a mental note to buy new clothes), he prayed that his new prank would work because he could not take much more of this.

When Tony went back to finish his breakfast, he noticed that a note had been stuck under his plate. He grinned. He was getting to her. He read the note over again. "What are you planning?"

Sorry for not updating sooner, I had midterms last week and couldn't find the time to write.
