Billy's daily Dad Jokes are an inspiration, so here's an opportunity for the Dads or Wannabe Dads-In-Spirit to add theirs. I'll start it off:

A man walks into an elevator. Goes down one floor, door opens and an attractive woman gets is.
She's looking at him, then she says, "Excuse me, can I smell your balls?"

"What??"

"I said, can I smell your balls?"

The man blinks and says, "Um, no."

"No? I can't smell your balls?"

"No, you can't smell my balls!"

Her rejoinder:

"Oh."
"It must be your feet then."
