Dear Dan,
I would never have guessed that you, our own Area Man, were such an able competitor for Joan's Geekhead President for Life title. Still, "laugh while you can, Monkey Boy." I'll bet you never won a free movie rental at Howard Hughes for *your* wife by knowing how long it took Han Solo to make the Kessel Run.
Melynda Huskey
P.S. I used that free rental on a *Metropolis/Cabinet of Dr. Caligari* double feature. But at our house, she who watches the towering works of German Expressionist film, watches alone. Everybody else was watching *Bulletproof Monk.*
