The 42-Year-Old Virgin - S3-E6

Continuity mistake: This episode reveals Stan has never killed anyone, even though he killed Jay Leno in Stan of Arabia: Part 1, killed Jackson's Double in It's Good To Be Queen, accidentally disintegrates one of his co-workers in I Can't Stan You, and shot a hang glider in An Apocalypse to Remember.

CIAPOW - S10-E2

Roger: Look at us, Steve. Neck and neck. May the best man win.
Steve: Well that's gonna be me, because your weird gut's about to hit the wall.
Roger: Not if your boner hits it first.
Steve: What? I don't have a boner.
Roger: You're about to.
Steve: How? What are you gonna do?
Roger: I don't have to do anything. You're a teenage boy who just heard the word "boner." It's already happening.
Steve: No. Not now. Not like this. Oh, God! Not like this! [Steve struggles to prevent his erection but it's heard hitting the wall.]
Steve: Damn it.
Roger: Yes! I won.
Francine: You did, Roger. But, in a way, I feel like we all won.
Roger: What? Wait, what?
Francine: Because it brought us all closer together.
Steve: You're right. I thought I was in a race, but really, I was in a family.
Roger: Okay, I see what's happening here. Yeah. You're trying to screw me out of my victory. We all heard his dick hit the wall.

Weiner of Our Discontent - S4-E18

Of Ice and Men - S2-E7

Question: Stan ditches Francine as a skating partner to skate with Roger because he's better than Francine and he does that because he wants to win the skating championship. Later in the episode, Stan realises it's not the winning that matters, then ditches Roger to skate with Francine not to win. But she declines. Why would she want to skate with him and not skate with him when he doesn't want to do it just to win?
