Dirty mind
If you see something different than Superman coming to rescue a crying boy then you know you have one.
There was this man who walked into a bar and says to the bartender 10 shots of whiskey.
A young boy enters a barber shop and the barber whispers to his customer, "This is the dumbest kid in the world. Watch while I prove it to you."
A little boy walks into his parents' room to see his mom on top of his dad bouncing up and down. The mom sees her son and quickly dismounts, worried about what her son has seen.
