We get a lot of great ideas from our customers here at I Heart Guts, but one of my personal favorites came from a dental student in Michigan, who begged us to make tooth t-shirts reading "Flossin' Ain't Just for Gangstas." Now while we still haven't made these shirts, I did make this one-of-a-kind drawing, along with a bunch of other special doodles -- including brains, lungs and kidneys -- all up for sale in the I Heart Guts store. Maybe you'll give one of these special friends a good home?
