In Lonely Island's song "YOLO," which they performed with the help of Jimmy Fallon on Fallon's show last night, the you-only-live-once mantra is given a, well, older person's spin. "Don't get too crazy/ It's not worth the risk... Never trust a bank cause they've been known to fail/ and never travel by bus, or by car, bus, boat, or rail." The song is on the fake band's new album, The Wack Album, and you can see the original video released in January here, featuring Adam Levine. [via Laughing Squid]
