Hufflepuff are just CRAZY. They really just don't give a shit. Oh it's got a Slytherin? Oh, look at it EAT snakes.
It's about time our yellow and brown friends become more than just "all the rest". They EAT snakes, actually exist (unlike griffins), and the Ravenclaw says "you do all the work, Hufflepuff, and we'll just eat what you find".
If you don't get the reference, watch this instructional video (warning: language): http://www.youtube.com/watch?v=4r7wHMg5Yjg
NOTE: ALTERNATE shirt available with "Hufflepuff don't care" on it instead, look for the other listing..
