I don't recall the gun. The program ended mere seconds after Danielson told the crowd to give BxB Hulk an ovation.
What a shame. I laughed my ass off. I don't remember when it was but when Danielson went to celebrate on a turnbuckle someone shot a confetti gun off. Besides the pure awesomeness of bringing a confetti gun to the show and the perfect timing on using the gun the look on Danielson's face was priceless. He legit looked like the happiest man alive.
