Little Johnny Sees Them Naked
Little Johnny has to stay at Grandma's for the weekend. Being an old school gal, bathing Little Johnny with her, Grandma sees no harm. So, there they are in the shower and Johnny points to Grandma's crotch and says, "Grandma, what's that?!?"
Grandma, somewhat shocked, quickly replies, "That's my beaver, Johnny."
"Oh, okay." And this answer seems to appease Johnny's curiousity.
Well, Johnny returns home, and one morning, Mom is running late for work. She decides that to save time, she'd bathe Johnny with her. Off to the shower, and once again, Johnny sees something not so familiar to him. "Mom, what's that?" asks Johnny pointing to Mom's nether regions.
Taken back, Mom says, "Johnny, that's my beaver."
Johnny replies, "I thought so. I think Grandma's is dead. Its tongue is hanging out and its all gray and wrinkled!"
