Mom 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 isn’t wearing any panties.

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?” the Mother replied.
“Because he has shit in one eye and blood in the other!”
