Jimmy Fallon, Seth MacFarlane Sing Holiday-Themed Yahoo! Answers on Tonight Show

Feeling festive! Jimmy Fallon was joined by Seth MacFarlane on Tuesday, Dec. 1, on The Tonight Show, to sing some holiday-themed versions of Yahoo! Answers — and it was pretty hilarious!

The musical duo sat at neighboring pianos and showed off their (questionable) piano skills and (real) vocal ability as they sang an array of bizarre questions and answers from Yahoo!

"What does TGIF stand for?" Fallon asked, flexing his vocal cords.

The top answer on Yahoo? "The Goat Is Fed," sang MacFarlane in response.

The answer to little BerryBanner23's question of "How does Santa know when I'm sleeping?" was even better.

"The same way Peeping Toms know. He looks in your window when you're sleeping. But when Santa does it, it's not weird," MacFarlane replied, in a tuneful voice.
