Johnny was playing outside when he had to go to the bathroom. He runs inside his house and his grandma was in the bathroom naked about to take a shower. He looks at her crotch and says, “Whats that?” She says, “Well, it's a beaver, Johnny.” The next day the same thing happens, only his mom is taking the shower. He says, “Mom I know what that is. It's a beaver, but I think grandma's is dead because its tongue is hanging out.”
