Readers, prepare to feel very old. It has been 25 years since Full House debuted on ABC, and as People magazine reports, the entire cast — minus the Olsens — recently reunited in LA to celebrate the sitcom that gave late ’80s/early’90s tweens something to do on Friday nights. The party sounds like it was just as wholesome as you would imagine; they all ate cake and danced to New Kids on the Block songs. But then, according to a tweet from John Stamos, he joined Candace Cameron Bure and Andrea Barber (who are both 36 now, if you can believe it) in some drunken karaoke. Unfortunately, the video that he shot displays sideways, but if you were a devoted Full House fan, consider it a very special clip that you can’t afford to miss. Check out the hilarious footage here.
