Green Day seems to be having a blast on their Hella Mega tour.

The band shared a clip today of a prank they played on Weezer during the last show of the North American leg of the tour on Monday.  Billie Joe and the guys crashed the stage at the end of Weezer’s set wearing strange costumes including a horse and a sea captain in a Speedo.

What’s the best prank you ever pulled off?
