A Pop Culture Reference of His Own

We often make fun of Harry because he misses many pop culture references. For instance, if you make shark music in the water (think Jaws) it does nothing for him. If you call him Bozo (not that we have, I'm just at a loss for good examples) he doesn't know Bozo is a clown. Anyway, if you hang out with us, you would know of some good examples, too. You may have even pulled a couple over on him. Whatever. He's good natured about it. Of course, he would get whatever, because Lightning McQueen says whatever.
Tonight, though, we have been preparing Harry to go to Wolf Trap to see Bill Cosby tomorrow.
Kind of hard since he doesn't know what a comedian is. Never saw The Cosby Show. T, for Temple U! is just a crazy song Mommy sings at bedtime... but, LITTLE BILL! Harry knows LITTLE BILL! We're going to see "the guy who wrote Little Bill!". He's downstairs now reading his Little Bill books.
