Grind (2003)

Other mistake: For the entire length of the movie, Bam Magera is referred to as Bam. But in the credits, his character's listed as Chad.

Continuity mistake: When Eric is battling the wigger kid on the halfpipe, the wigger's skateboard changes. When he's just standing on the top of the ramp, it's a World Industries board, but when he's doing tricks it's an almost all black skateboard.

Continuity mistake: When the four main characters clean out all the debris in the motel's dry pool, the sunlight angle doesn't change at all, even though it had to be several hours' worth of work.

Dustin: Lil Bow Wow, you keep barkin', you and I are gonna take a one way walk into the woods.
