"The Spudheads"

Larry, Moe and Curly. Oops, I mean Gary, Bill and Stephan.
Gary is the "Head" Potato Head
Bill is the "Cute" Potato Head
and Stephan is the "Imported" Potato Head

Actually, these guys work in the Plant Pathology section of the Department of Plant Sciences and do research on such things as "Potato Late Blight".
