"Tonight Show" and former Onion writer Mike DiCenzo teaches us how to kill it at karaoke, how to accidentally write a song with Paul McCartney, how to become friends with the cast of "Saved By the Bell," how to get dad jokes into The Onion, and most importantly, how to do a showstopping performance of "Super Bass." Plus we play "F-Marry-Kill" with beloved 90s TV characters. Would you make love to Urkel? The answer might surprise you.
