Doing a walk-a-thon for charity? Running a marathon? The organization Mustaches for Kids raises money by asking men (or ladies willing to forego an upper lip wax?) to grow out their facial hair. Now it's set up shop in Baltimore and is looking for "growers" and sponsors for those who grow mustaches from Nov. 12 to Dec. 13. No trimming allowed! (But you do have to shave the rest of your face.) Growers must check in weekly to have their facial hair examined and at the end appear before a panel of judges. Participants solicit donations from friends, family and co-workers.

Money raised will go to DonorsChoose.org, the Web site that funds the classroom wish-lists of Baltimore teachers. Last year, DonorsChoose says, it sent more than $200,000 to city classrooms for 558 teacher requests ranging from pencils and paper to butterfly habitats and ant farms.
