Torrey Pines looked more like the set of "Happy Gilmore" on Friday ... 'cause Brooks Koepka hit a tee shot that landed INSIDE a shoe -- and it had everyone wondering, should he have to play it as it lies?!?!?!
The wild scene all went down during the 2nd round of the Farmers Insurance Open, when Koepka smashed a drive down the right side of the fairway that crash landed into the back of a golf cart.
As Koepka strolled down the North Course's 16th hole ... the 30-year-old quickly realized the ball actually came to rest IN a shoe that was sitting on the back of the vehicle!
