The Take Me Fishing people have a set of YouTube viral videos showing all kinds of trick casting. I'll embed my two favorites:
Master Casters - Thumbs Up (via takemefishingfilms)
Master Casters - Skeet Fishing (via takemefishingfilms)
I don't see these guys pulling off the trick that I seem to pull off whenever I go fishing, which is to lose lures and hooks on random debris and occasionally cast a line only to watch my lure fly into a lake or stream unfettered and free from my tyrannical ways.
