As Jalopnik's resident expert on screaming like a 12-year old girl in the back of a cab, I know a good cab prank when I see one. And this snake in a cab prank is good. It's funny when it isn't you!
This prank is simple, since you don't need a Jeff Gordon or a closed brickyard set up for stunt driving. Nope. All you need is a taxi and an albino boa constrictor. Then you need to pick up passengers.
And that's when the hijinks begin. Sit back, relax, and be glad it isn't you shitting your pants. I know I'm grateful it isn't me.
