Dave got upset that Opie treated him like a stuntboy, so he came up with an over the top stuntboy character that he wrote two jokes for and repeated for 4 hours.

Dave had a crude, but funny, bit that he drove into the ground.

I dont remember what clip it was but he came in and started yelling about cum and scabs
