Jonny asked where he got it and Timmy said “last night I walked into my parents room and they were naked on the bed having sex, my dad gave me his watch and said “TAKE THIS AND GET OUT”.
Little Jonny wanted a new watch too so that night he decided to go into his parents room to try and catch them in the act.
As he walked into his parents room, they were hard at it, and his dad turned around and said “WHAT DO YOU WANT JONNY”? Jonny replied: I wanna watch!
His dad said “Then sit down in the corner and shut up”!
