Janeane Garofalo and Rob Cohen unwittingly wed for 20 years Actress Janeane Garofalo, the voice of Colette in the Pixar animated motion picture "Ratatouille," arrives for the premiere of the film at Grauman's Chinese Theatre the Hollywood section of Los Angeles on June 22, 2007. NEW YORK, Nov. 14 (UPI) -- Actress Janeane Garofalo says she didn't realize she and producer Rob Cohen were legally wed after drunkenly swapping vows in Las Vegas 20 years ago. "Rob and I got married, for real, which we had to have a notary dissolve not 30 minutes before we got here tonight," UsMagazine.com reported Garofalo told the crowd at a New York Comedy Festival event celebrating the sketch comedy series "The Ben Stiller Show" during the weekend. We were married for 20 years until this evening. We got married drunk in Vegas. ... We dated for a year, and we got married at a drive-through chapel in a cab. [We thought] you have to go down to the courthouse and sign papers and stuff, so who knew? We were married, and apparently now that [Rob] is getting married for real, his lawyer dug up something. Cohen and Garofalo were both writers on "The Ben Stiller Show." Garofalo also appeared on the series. Cohen, now a producer on "The Big Bang Theory," is engaged to "Jimmy Kimmel Live" producer Jill Liederman, the New York Post said.
