I drive by this Old Chicago sign almost every day.
Every month or so a new slogan (that includes the words "pizza" and "beer") is displayed on the over-head, and they're all pretty witty. For example, their Christmas sign read: Dasher, Dancer, Prancer, Comet, Cupid, Pizza, and Beer.
Stupid? Yes. Fun? Yes.
I can't help but be excited for the next installation :)
