"Oh no!" cried Karen. "I forgot to wrap one of your presents!"
Fortunately, I'd read ahead on my Dilbert desk calendar. Sunday, Dilbert will suggest to his mother that, since it's silly to take the time to wrap a gift that'll just be torn open thirty minutes later, perhaps he could just wrap her present in a towel. And since he didn't want to lug a towel all the way over to her house, maybe he could use one of hers.
While Dilbert's mother didn't seem too keen on the idea, it worked fine for me. And though Karen accepted the idea, it distressed her that we didn't have any towels in Christmas colors.
