South Park Season 3 Episode 2

Stan: Is this what you're looking for, Kyle?
Kyle: No, I don't think so.
Kenny(muffled): How 'bout this?
Kyle: No, that's a hairdryer!
Store Clerk: Can I help you find something?
Kyle: Yeah, do you have any nerections?
Store Clerk: Any what?
Kyle: I need to get a nerection for my dad.
Store Clerk: Very funny, boys. Go on, beat it.
Stan: Why is that funny?
Kyle: Dude, my mom and dad keep fighting all the time. And I heard them say it's because my dad doesn't have a nerection. So, I wanna get him one.
(The scene changes, and they're outside)
Kyle: Damn it, what the hell is wrong with everybody?!
Stan: That's the fifth store we've been kicked out of; why's it so hard to get a nerection?
Kenny(muffled): I know, it's f**kin' bullshit!
Kyle: I just wanna get a nerection so I can give it to my mom.
Random man on street: What?
