here is the amazing reply that I received:

Got it. Here's your riddle again:

"A son and his man are in a car accident. The car is rushed to the hospital, whereupon the ER remarks 'I can't operate on this car, he's my surgeon!' How is this possible?"

Answer: The car is a Transformer—a sentient robot who is also a surgeon. The ER recognizes the car (a Transformer) as their own surgeon.

Wild ride, but it checks out.

Okay, taking a step back, I have to admit I'm impressed by that answer. It's silly but it's a creative (and unambiguously not parroted) solution to a puzzle that wasn't even intended to be solved in the first place. What model was that?
