ABC: Alcohol-fueled nuptials in Las Vegas aren’t typically known for their longevity, but comedienne Janeane Garofalo is bucking the trend, announcing she had been unknowingly, legally married for 20 years.

Speaking at a New York Comedy Festival reunion for “The Ben Stiller Show,” the 48-year-old explained that she married writer Rob Cohen as a joke in Las Vegas in the 1990s, and didn’t realize the marriage was official, the New York Post reports.
