It's almost a year-old, but absolutely brilliant prank here. Jose Barrientos spent an entire semester pranking his public speaking 101 class into thinking he had a Mexican accent. In his final speech, he revealed that the accent was phony and all an act. People's minds exploded, except the catty blonde who said she knew he was fronting all along. Yeah. Right.
But seriously... If you're willing to commit yourself to a 12-week prank, this is a pretty solid move for anyone who just wants to troll the hell out of their requisite gen-ed speech class. I'd love to see an American English speaker try to pull off an Australian exchange student for that long.
