This internet video of people pleasantly ordering their McDonald's combo meals to a Jason Mraz tune is what I'd call an awesome prank.
And if by awesome prank, I mean "really getting" people by ordering a Big Mac to the tune of a song a couple of my friends danced their wedding dance to that's hardcore because a couple of friends own flip cams aren't held down by the man, while you're all brunching eating bats and talking about silly insane ideas, you come up with this crazy idea and put it on tape. The cashier lady even joins in on the prank because you're all so likeable badass.
WAY TO PRANK 'EM, dudes!
You got em guys! Next trick: the INTERN CHAIR! Hahahhaahahhaahahhaha! Watch out! Pranksters on the loose!
