Oh, for funny moments, with Tyrande they are abundant. Seeing enemy heroes escape past their walls with like 1/10 of their health and they're probably happy they escaped and are about to teleport home? Yeah, I've become an expert of killing them with the owl just before they would be ported out. Funniest thing ever, I even imagine their thoughts "phew, I'm safe, teleport to heal then... noooooooooooo!"
