A hunter kills a deer and brings it home. He decides to clean and serve the venison supper. He knows his kids are fussy eaters, won't eat it if they know what it is - so does not tell them

His little boy keeps asking him, "What's for dinner?"

"You'll see", says his dad. They start eating dinner and his daughter keeps asking what they're eating.

"Ok," says her dad, "here's a hint: Its what your mother sometimes calls me."

The girl suddenly screams at her little brother, "Spit it out! It's asshole!"
