Watch What Happens Live was on fire last night. No, seriously.

During the after-show, the building's fire alarm began blaring saying that they were investigating the situation. In true Andy Cohen fashion, he declared that every time the alarm sounded, viewers had to take a swig of their drink. But the fun was short-lived, as the entire building had to be evacuated shortly after -- and you'll see Andy, Jeff Lewis and Jenni Pulos taking the stairs like good fire evacuees. The brave fellas of the FDNY quickly arrived to assess the situation, and thankfully all was fine.



And because he's a consummate showman, the audience and people on the street kept the fun going outside, as Andy and guests Jeff and Cloris Leachman made the best of the situation and posed with the fire truck. Check out the gallery below!
