It seems that when "comedy" writers for current movies run out of ideas (usually within the first five minutes or so), they figure it's time some male cast member took a shot to the crotch.

Could someone tell these imbeciles that was worn out the second time it was used?

Perhaps a better approach would be to walk up to the writer, kick him in the groin, and then say, "You're right. That IS funny!" After that, he probably would reconsider his choice of material.

Holding a gun sideways and/or one handed and expecting to hit anything at all, even if it's 10 ft away. Especially if the character doesn't have any sort of practice with a firearm. If someone's shooting at you, you hope he's holding the thing sideways - better chance of shooting his henchman, or the dog two blocks over than you.

Anyone holding a weapon that way automatically identifies themselves as a firearms moron. You couldn't hit squat deliberately by holding a weapon that way.
