So a young boy begs his parents for the new talking robot friend. He gets the robot and on the first night, hes at the table with his dad, and the robot is there, so dad says:

your mom tells me youve been reading those porno mags again !

boy: no dad, I swear I didn't

so the robot rolls over to the little boy and slaps him upside the head (sorry for the violence)

dad: you see, I didn't tell lies when I was your age.

The robot rolls to the dad, WACK upside the head

So the mother in the kitchen starts to laugh and says out loud:

Isn't that your son !

The robot goes to the mom...wack!
