name that movie

I must have a strange vocabulary of movies. Some radio station had a "name that movie" contest, and I found myself surprised that I was the only one who knew it: Friday. Or earlier, a colleague was telling an anecdote about someone with a short term memory and said, "You know, like that movie where that person can't remember anything for very long." "Memento?" I ask. But no, she's talking about 50 First Dates with Drew Barrymore. Slight difference.
