Post Malone wants to make his fans feel like rockstars (just like him!) by giving away a Bentley.
The rapper, 23, is asking fans to donate $10 to the nonprofit Folds of Honor, which provides educational scholarships to families of deceased and disabled veterans, for a chance to win the $200,000 car. To promote the cause, Malone went undercover — to the best of his ability, given his face tattoos — in a record store in Los Angeles.
A video on the musician’s YouTube account shows him wearing a white flat-brim hat and a polo shirt buttoned all the way so he blends in as a salesman. While a few shoppers recognized the “Better Now” hitmaker almost right away, he successfully pranked multiple people by showing them his breakthrough album Stoney and declaring that “it sucks.”
He also convinced a couple of strangers to workshop some lyrics — he was told he “needs more Jesus” — and help him come up with a rapper name. When one man told him to just put “Young” in front of the last thing he bought, Malone’s response was hilariously NSFW.
At the end of clip, unsurprisingly, he’s fired.
