The felt is cut into mustaches by Technigraphics in Hunt Valley and the art and packaging in small zip-lock bags is done by Peabody Press in Baltimore. Inserted into each plastic bag is a card with instructions on how to apply Fanstaches and disclaimers such as "Wear Fanstache at your own risk," and ""Fanstache is not for human consumption."

The neighbors trademarked the word "Fanstache," and the familiar letters "TM" appear next to each reference. They've also deleted early references to the Super Bowl, a name owned by the National Football League. They've even made a promotional You Tube video ("It's silly," said Josh Griffin) and printed posters and T-shirts to promote the fake Fu Manchu mustaches.

"Chu want one?" the T-shirts ask.

"We're trying to get (customers) to send in pictures of themselves wearing their Fanstaches, to create some team spirit here in Baltimore," Schauman said. "The goal is to keep it going all the way to the Super Bowl."

Customers, from as far away as Florida and Georgia, are heeding the call, buying Fanstaches for playoff parties and tailgating events, and e-mailing photos of themselves wearing the mustaches. One sent a photo of a cloud in the shape of a Fu Manchu. Another shows a dog wearing a Fanstache.

One wiseacre sent a doctored photo of Hines Ward, a star receiver for the Ravens' division rivals, the Pittsburgh Steelers, "wearing" a Fanstache.

Kim Meagher, a volunteer for the Ronald McDonald House in Baltimore, sent photos of seriously ill or injured children wearing Fanstaches.

Josh Griffin said he emails "a personal shoutout" to all Fanstache buyers, thanking them for their business and for supporting the Ravens and Living Classrooms. Invariably, the customers write back, and many say they're planning to go to the Ravens game or to parties.

Keeping it going

The $5 selling price is about $4.50 more than the cost to make each mustache, Schauman said. The notion of making a little money for themselves is appealing, he admitted.

"We've worked hard on this," Schauman said. "We've had a hard time sleeping at night — and eating during the day."

Josh Griffin envisions keeping the business going with other teams and other sports and supporting other nonprofits and charities, such as Ronald McDonald House.

But the partners said their business, at least for now, is less about making money than it is about supporting a good cause, Living Classrooms, and fostering Ravens fever for what they hope will be a successful run for the home team through the playoffs. That quest begins Jan. 15, when the Ravens, who earned a bye last weekend, will host the Houston Texans.

"If we can write Living Classrooms a nice check, that means more," said Jason Daly.

"And it would be nice to win the Super Bowl," Schauman said. Then he corrected himself.

"I mean, the Chu-per Bowl."
