Using some of his free time to have some fun, Pittsburgh Steelers running back DeAngelo Williams went undercover at a Pittsburgh-area Dick's Sporting Goods store.

The result: an entertaining video.

Williams posed as a Dick's employee and interacted with shoppers. The Steelers running back handed customers their items and even wrapped some gifts, which turned out to be quite an adventure.

None of the shoppers appeared to have any idea who was assisting them until Williams decided it was time for the reveal.

Williams' little stunt turned an ordinary shopping trip for customers into an unforgettable experience. Of course, he also looked like he was having a good time with the prank.
