Professor McGonagall

Nobody knows whether Greg has actually read a Harry Potter book - or seen any of the movies - but that hasn't stopped him from donning a dollar store witch's hat and cloak, and becoming the one and only Professor McGonagall. Despite wielding his wand with the confidence of an egg-tossing champion, Greg seems to have no latent magical abilities, instead using his theatrical hand-waving and shrill voice to subtract and add (but mostly subtract) points from the rest of the Kinda Funny crews' Hogwarts houses.

Of all of Greg's personas, Professor McGonagall has been around for especially long, suggesting that he has probably been practicing this act since early in his IGN days. Indeed: if one were to travel back in time and peer into the media giant's offices circa 2009, one would probably witness Greg prancing through its halls as the Hogwarts professor, with Chris Roper and Jeremy Dunham yelling at him from the sidelines to return to his desk and review Marvel Ultimate Alliance 2 for the PSP.
