No one taught Regis Philbin about stranger danger -- the iconic TV host hopped into a random van in New York City when he couldn't hail a cab … and it's all on video!
It all went down Wednesday afternoon ... when two guys happened upon Regis standing in the street, trying to get a ride.
Reege must have been in a crazy hurry, because he took the guys up on their offer for a lift. Check out the photo below ... he wasn't exactly hopping into a town car!
Despite the creepy unmarked van, Regis got where he needed to go -- 8 blocks away -- in one piece.
Don't try this at home, kids.
