Pranks have become common among Country Stars out on the road.

We've heard from Brad Paisley's guys rubbing stinky cheese on Darius Rucker's microphones and Taylor Swift  got back at Keith Urban one night dressing her band up at the rock group KISS and joining Keith on stage but this might be a first.

The boys from Love and Theft and Florida Georgia Line came out on stage as Jake Owen was singing his nightly encore, "Jump" wearing only UNDERWEAR! See for yourself!
