I have a wiseguy coworker and longtime friend who sees setups in everything- it's a challenge to say anything around him that he can't turn into a punchline! One day, I'd just moisturized my hands with a bit of baby lotion when my officemate entered with Wiseguy in tow. Officemate paused, and with a puzzled look, asked, "Why do I smell baby butts?", to which Wiseguy quipped, "I dunno- character flaw?"
