A kid comes home from college. His father is a farmer, and he's shoveling all the manure out of the outhouse onto the hay crop to fertilize it. The kid says, "Hey, Pop - I learned in college that there is an easier way to do everything."
They go into town and get some dynamite. They're gonna rig it up under the outhouse and blow the manure into the hay field. They get it all rigged up, but they don't see Grandma coming to use the outhouse. Ba-Booom!
The manure goes flying, and so does Grandma. Ploop! She lands in the hay field. They go running up to her. "Grandma, Grandma! My God, are you alright? Are you alright?"
She says, "Yeah, I'm fine. Phew! I'm certainly glad I didn't let that one go in the kitchen!"
