NO ONE ever doubted that NBC's "The Tonight Show" would go big for Jimmy Fallon's first night. But U2-on-the-roof big? That was a cool stunt. Hypothermic even.
Fallon was his charming, disarming "Late Night" self in a classy new setting, dancing with Will Smith, schmoozing with Bono. And while I'm still scratching my head over Kim Kardashian's appearance in the parade of celebs, from Robert De Niro to Lady Gaga, paying off a mock bet that Fallon would never host "Tonight," the bit paid off when Fallon's time-slot rival Stephen Colbert hauled in that bucket of pennies to "welcome" him to 11:30.
