Ty and Spike wrote a little dialogue for him and emailed it to him, and he was pretty baffled by all the lingo and stuff he had to say, so they explained it to him and I guess he prepped for the "role."
He did really well. I was impressed that Koston was able to switch outfits that quickly. Plus the jazz push and the sudden toe drag after the noseblunt to slow down was always funny. There's a lot of little funny moments from that skit, like how he says Spanky bluntslid that rail in TIS, but he actually did a front feeble down it. Or Carroll's casual indifferent behaviour.
