Yuck, I would hate that job! I doubt that stuff tastes very good. On the flip side though I bet your insides are all nice, polished and hydrophobic. Furthermore, I bet the guys that win those Nathan's hot dog challenges are secretly taste-testers for Menzerna!
They should do some blood work to see if their blood-type comes up PO85RD
