Rapper Dresses As An Old Man, Drops Some Sick Rhymes On Unsuspecting Listeners

'He's probably going to talk about wet farts.'

New York, beware! Coby Persin and his rapper buddy Hi-Rez are at it again.

These two pranksters already made a name for themselves with their last collaboration on "How To Order Mcdonald's Like A Boss," which was nothing short of incredible. Now the duo is back with a new video that'll not only make you ROFL, but appreciate the older generation as well.

For their latest stunt, Hi-Rez, 21, underwent a serious makeover and transformed into an 80-year-old grandpa. The two then hit the streets of Harlem looking for unsuspecting people who'd like to hear this old man rap. 

Needless to say, everyone was skeptical of his performance at first. But just as Hi-Rez started spitballing, they had to scrape their jaws off the ground.
