Two of country music's biggest stars are on tour together, Brad Paisley and Blake Shelton. You may or may not know that both Brad and Blake share a healthy sense of humor and are huge pranksters. In fact, both love trying to pull off any gag that will embarrass their fellow tour mates.

Mix in a birthday while they're on tour and... well, you never know what might happen on stage. Especially when your friend and tour mate is one of country music's most notorious and creative pranksters, that would just love to embarrass you in front of your fans.

Saturday was Blake Shelton’s 35th birthday and his buddy Paisley was good enough to get him a special gift during the show! As if that wasn't enough, Brad then tweeted a photo of it to the world.
