Seriously... he and Barbara Streisand were in a porn flick together called the "Italian Stallion". But you probably won't find this movie around anymore, as Sly and Barb spent alot of moolah getting every copy destroyed once they became famous.
My favorite part of the movie was when he slapped her in the side of the head for scraping her teeth on his yogurt slinger while she was giving him a bj.
God, I can barely understand Sylvester Stallone when he talks, it's like trying to hear a New Yorker talk with an uncooked potato shoved in his massive mouth.
Interviewer: "So Mr. Stallone, what do you like doing in your free time?"
Sylvester: "Wehl, when ah roowy wink amun it, I foon marself moha junoso munuh, mespooshally quantum biomechanics".
