Snooki and The Situation can't seem to agree on exactly how long ago they hooked up. The Situation seems to believe it was much more recent than Snooki does.

"You are lying about me hooking up recently with you," Snooki yelled on last night's Jersey Shore.

The Situation yelled back, "We hooked up two months ago."

The problem for Snooki is that two months prior to filming the show, she had a boyfriend.

"You're psycho!" Snooki screamed. "You're f***ing psycho! Get over it. Nothing happened."

"Two months ago," he repeated. "I'm not going to lie."

"You know how much I f***ing love Jionni and the fact that you would say something like that, you are a expletive," Snooki said.
