The Old Wiley Coyote Switcheroo
This prank seems kinda road runner/ wiley coyote-ish.
You get someone to ride a bike or motorcycle perhaps during night-time, possibly in a race.
But you get a huge ass painting of what looks like the road and its surroundings so when they're traveling top speed they'll crash into it.
I would prefer to see this happen to Ryan Dunn :D
