Zonker: What's it say, Dad? Is somebody sick? Man: No, it's from Duke! He's coming in today! Zonker: Uncle Duke? Why isn't he at his post in China? Man: Guess he was relieved... Zonker: Darn! What a time for him to come visiting! Right in the middle of my tanning program! Man: But he is your uncle, son. Couldn't you take a few days off? Zonker: Are you kidding? And risk peeling?! Man: Can't you go on emollients?
