it's my life

Three little boys were sitting on the porch, when one little boy says, "My Daddy smokes, and he can blow smoke rings."
The second little boy pipes up, "Well, my Dad smokes, too, and can blow smoke out of his eyes."
Then Little Johnny, not to be outdone responds, "My Dad can blow smoke out of his butt."
"Really, have you seen it?" reply the boys.
Little Johnny responds, "No, but I've seen the tobacco stains on his underwear..."
