Little Johnny's mother was standing at the sink one morning washing dishes in her gown. Little Johnny came in, raised her gown and looked under it, and she wasn't wearing any panties.

Little Johnny asked his mother, "What's that?"

She replied, "That's my beaver."

Little Johnny took another look and said, "Mom that must be one mean Son of a Bitch."

"What makes you say that?" his Mother replied.

"Because he has shit in one eye and blood in the other!" replied Little Johnny.
