Firing into melee with a missile weapon. Has there ever been a situation guaranteed to provide more amusement than that?

We mean melee involving at least one friendly character, of course. Firing into a melee made entirely of enemies is no fun at all. (It's much more amusing to blast the lot with an area effect weapon or a fireball, for example.)

Because everybody just knows that you're going to hit your comrade. It always happens. And yet people try it anyway. Because it's so much fun. If you hit the enemy, that's fine, you score a hit and do damage, and possibly go on to win the encounter. But if you hit your friend, that's hilarious. It's the ultimate win-win situation!
