I have many. I feel so stupid sometimes watching a movie that I have on video or DVD right in front of me, but yet I'll sit there through all the comercials. DUH.
Anyway, any of the Predator movies I'll just watch no matter how many times they come on.
White Men Can't Jump I know almost word for word.
Bruce Lee movies, again word for word.
The older Postman Rings Twice also gets a nod.
And much as I HATE to admit it, Ghost and Dirty Dancing gets airtime everytime.
No matter how much I hate to admit it.
