In the scene when Baby D chases Day-Day outside (in the back parking lot) the first time when Craig, D-wana, & Roach come out to watch, you'll notice Roach's skateboard is in his left hand. In the next sequences, you'll notice his skateboard is now in his right hand! I'm sure he wanted to watch what was happening & not put the board in his other hand when his buddy was going to get jumped by his girlfriend's BIG sister.
