The host of NBC’s “Late Night with Jimmy Fallon” celebrates his birthday today. Jimmy’s clever impersonations landed him a pretty good gig in 1998, and he remained a staple of “Saturday Night Live” until 2004. He’s starred in the movies Factory Girl, Taxi and Fever Pitch. On June 12th of this year he released a comedy album titled “Blow Your Pants Off.” It features guest appearances from Paul McCartney, Bruce Springsteen, Justin Timberlake and Dave Matthews. Today is also the birthday of a long-time soap opera star. Alison Sweeney has portrayed Sami Brady on “Days of Our Lives” since 1993. She has hosted “The Biggest Loser” since 2007. Both Fallon and Sweeney are in their 30s. Who’s older?
