Insufficient Ammo

Okay, listen up, you little smooth-brain. You posted a joke where a dude with a gun is all mad about his wife, and the bartender's like, 'lol, your ammo's insufficient'. It's funny because it's a huge exaggeration and makes it seem like a bunch of dudes were with his wife, way more than his gun can deal with. You would think the man should be concerned about his wife's safety instead of seeking revenge. I hope you understand now.
