Cleatis and Emit

My husband is teaching a graduate class in Thermodynamics.  It's mid-term time and one of the questions he's giving them has to do with two guys and a distillery.   He asked me if I could draw a picture to go with the question, and being the sweet and wonderful wife that I am, of course I said "yes.   I had fun drawing Cleatis and Emit; hope the Thermo students enjoy them too.  :)
