In the segment, the Mandatory Fun singer added his own spin to the opening theme of Mad Men, singing "Jon Hamm's never won an Emmy/Oh, who cares, he's still Jon-freaking-Hamm." Throw to a shot of Hamm agreeing, yes, he is in fact Jon-freaking-Hamm.

He then revamped the themes to Modern Family, Scandal and Homeland singing "Inigo Montoya grew a beard!" The best moment though had to be his take on the Game of Thrones theme song. Though he did not dedicate the nearly two-minute long theme to Peter Dinklage (that's already been done) he did draw attention to GoT's staples: dragons and boobs. "Here come dragons galore/And some boobs," he sang. "OK, to be fair, there's way more boobs."

He then George RR Martin, the man behind A Song of Ice and Fire series, which is the inspiration for the HBO show, to get writing and quick to finish the last books. Even delivering a typewriter right to his seat so he could work during the show. Martin played along, typing on the archaic looking machine.
