Up north at the resort I work at (with 24 other guides) we've been known to play a few practical jokes, 1 that I've pulled off a time or 2 is to zip tie another guides net to his hand rail (when he's crew fishing, not with guests) with a little bearing grease on the handle.

While fishing with other guides you never turn your back on any of them while fighting a fish as your reel my be thrown into free-spool at any time.

Any time you get the chance to smash another guys freshly baited hook, you take it, especially if there's a hot bite going on.
