John Pinette made some joke on one of his DVDs about how some of his friends tell him that when he starts working out, he won't be able to stop after a while--it'll become a habit, and he says he's not like that woman (he gives some name) saying, "Oh my god! I'm having so much fun! I just can't stop!!"
Er something along those lines. It's funny. Guess you just have to see it.
