Boy is forced to eat poop prank. (boy is confused if it's real or not)

This boy thinks his dad is really going to feed him poop. He doesn't know it's a prank with peanut butter. When he is forced to eat peanut butter (poop) he knows it's peanut butter and goes to eat more, but when his father keeps saying it's poop the boy gets confused and starts to get really upset because he doesn't know if it's really poop like his father says or peanut butter like what it tastes like. Too funny!
