Be polite when you potty.
Two guys come home from the grocery store and see a third guy standing in the front yard of one of their houses, urinating. They tell him not to do that because there are children in the house. Plus, they probably already fertilized the lawn this year.
So, the peeing guy take offense at being told where the hell he can pee so he pulls a gun and . . .
The gun jammed and no one was killed, but the homeowner caught three slugs.
