When Cleveland finds out that the homeless are getting gourmet food fixed by Stoolbend's top chefs in "'Tis the Cleveland to be Sorry", he passes himself off as homeless to get in on the goods. The shelter residents look after him after he spins a yarn about being a Vietnam vet but is caught when Donna nominates him as a Stoolbend angel for the work he claims he is doing at the shelter and is exposed on television. "The Prof" is voiced by David Costabile.
