Corey was warming up before a match (just throwing nine balls out and making them in order) and was faced with this shot - nearly straight on against the five, and the bank closed due to three blocking balls.
Instead, Cory did a mini-jump into the five, which jumped the five slightly against the rail, where it rebounded and flew all the way across the table (albeit at a very low height) directly into the corner pocket. He did it while chit-chatting with a pal and without giving it much thought and his usual four whole seconds of pre-shot routine.
The friend's remark? "You're sick, dude. Just sick."
P.S. This is probably something almost every capable pro could do, but I'd never seen it before and it was quite impressive.
