Oh, I had to smack son... repeatedly. He made a chocolate microwave dessert thingy. He stuck his finger in it and licked it. Why do guys do that? Anyway, there's still chocoate on his finger and his hand heads towards his pants.
"Don't you even think about rubbing that on your pants!" as I hand him napkin.
"Ok, how about this instead?" He wipes the chocolate down the cheek of his face!!!! Twerp! I was laughing and smacking him at the same time.
On the bright side, he almost pass the dessert through his nose because he was laughing so hard.
