Okay, some of the following lines are really cheesy, and there's no doubt about that. But other lines are just fucking epic. A few of them I would even call classic. ("I came here to kick ass and chew bubblegum. And I'm all out of bubblegum." and "Pain don't hurt" are among my favorite).
Also, there's one where two gorgeous young men are clearly getting ready to fight something and one says to the other "In case we don't make it, I just want to say, you've got the biggest dick I've ever seen." What movie is that from? A friend wants to know.
Towards the end, there's a great line from John Barrowman. It wasn't in the script. He just ad-libbed it because the actress NEVER cracked a smile. She didn't smile then, either, and the director decided to keep it because he didn't feel like shooting the scene again.
