Ellen Degeneres likes to play pranks on her guest stars. In particular, she enjoys frightening the living daylights out of them by having a clown or other dressed up character suddenly appear during their interview.
But recently when she had Niall Horan appear on the show, she decided to tailor the fear factor to the One Direction star by recruiting another One Direction star: Harry Styles (a lookalike, anyway).
While Niall was on the couch chatting away to Ellen, someone dressed as his bandmate jumped out of a box and frightened the poor little Irishman.

Poor Neil never saw it coming...
