Jimmy Fallon, the fun-loving host of "The Tonight Show" on NBC, recently ignited a full-on "Grease" sing-along in a New York City bar.
Per TMZ, Fallon stopped in Marie's Crisis Cafe in the West Village to have a few drinks with fellow guests. However, a simple beer or two apparently wasn't enough.
Joining in with Fallon, the entire bar began to sing "Summer Nights," which was also the same song the NBC frontman sang on his last "Saturday Night Live" show in 2004, as seen in this Buzzfeed post.
