Statesman reader Alan Harkness nominated the distinctive, rotating sign "that's been informing and entertaining us for generations."

The sign at a prime Front Street viewing spot for commuters regularly features jokes and one-liners a la Reader's Digest.

A typical example: "If wool shrinks when it gets wet, why don't sheep shrink in the rain?"

Joe Schmoeger founded the company in 1949, his grandson Eli Schmoeger said. Eli now runs the family business, which provides cleaning and janitorial services.

His granddad was known for his wit, said Eli. Joe started the tradition of posting jokes on the company's sign. These days, choosing quips is a group project. Employees and staffers compete to get their jokes posted.

"Everyone wants to be published," said Eli.

The community gets involved, too. People call to submit ideas for the sign. If the sign poses a question, chances are people will call or stop in to answer it, say staffers.
