It's been a long time since we've stumbled across '80s star Steve Guttenberg, known for his hit movies "Police Academy" and "3 Men and a Baby" (also that stint on "Dancing with the Stars" in 2008).

But the actor showed up to a New York Knicks game at Madison Square Garden last night, with none other than Liam Neeson and his son!

Steve was a good looking guy back in the day, so we were a little…well…surprised to see these pictures.
