Joe Dirt: So, you're gonna tell me, that you don't have no black cats, no Roman candles, or screamin' mimis?
Kicking Wing: No.
Joe Dirt: Oh come on man. You don't got no lady fingers, buzz bottles, snicker bombs, church burners, finger blasters, gut busters, zip-a-dee-do-dahs, crap flappers?
Kicking Wing: No, I don't.
Joe Dirt: You're gonna stand there, owning a firework stand, and tell me you don't have no whistling bungholes, no spleen splitters, whisker biscuits, honker lighters, huskers dus, husker don'ts, cherry bombs, nipsy dazers, with or without the scooter stick, or one single whisking kitty chaser?
In the scene just after Joe finds his parents, when they are sitting in their trailer talking, his parents have a stuffed clown between them. Just before Joe asks them if there ever was a time when they'd be staring at the moon, the clown is slumped forward with its face not visible. In the next shot, when his mom starts her sales pitch about having clowns for sale, the clown is now standing upright between them.
When Joe Dirt finds out where he lives in Louisiana, there is a guy (Framer Fran) that speaks very strangely. He is played by Blake Clarke who played the same farmer character in The Waterboy.
