This is one of the most valuable logos in all of college sports. This logo, which debuted in 1965, has got it all: a drunken, pugnacious, wearin'-of-the-green leprechaun puttin' his dukes up. (Do Irish-Americans drop their terminal "G's"? Guess so, judging from this ...) It's even got subtle cultural signifiers like St. Brendan's haircut. The only things missing are red hair (which wouldn't fit ND uniforms' green, gold, and blue color scheme) and a knocked-over barstool.
