Aidan Gillen as Littlefinger + Michael Coleman as Mr. Baelish – Celebrity Doppelgangers

Winter is coming (at least in the 'Games of Thrones' land of Westeros), but for high schools across America, prom is coming. Hence the arrival of the YouTube parody 'School of Thrones,' and the best Lord Petyr "Littlefinger" Baelish look-alike we've ever seen, Michael Coleman.

Not that we've seen a lot of Littlefinger cosplay or anything. Okay, maybe like five.

Irish actor Aidan Gillen plays the devious Littlefinger, the character everyone loves to hate (well, aside from King Joffrey "my uncle is my dad" Baratheon), on HBO's hit show 'Game of Thrones.'

Playing the hopefully less devious but apparently just as creepy Mr. Baelish at Westeros Valley High on the brand-new YouTube series 'School of Thrones' is Michael Coleman. Who is pretty much the epitome of perfect casting.
