Dirty
A guy joined a nudist camp and when he told his mom she didn't believe him. 
So he sent her a picture of his top half. 
A week later his grandma wanted a picture but he accidently sent the bottom half. 
Knowing she had bad eyesight, he didn't think much of it.
A week later his grandma wrote a letter saying, that she didn't like his haircut, because it made his nose look too big.
