what am i going to do with you?

"What am I going to do with you," I said to Bean last night as we were finishing dinner.
"Smack me on the head!" was the exuberant reply I received.
I laughed...and felt slightly concerned... so i said, "why would you say that?"
"cuz it funny," she says roaring with laughter.
I just laughed. I have no idea where she got that phrase or why she thought it would be so funny, but I suppose it's my fault for asking. It was pretty funny. :)
