...Zebra did it.
"Ha ha ha," the club manager spat, "that has to be the most tired joke I've ever-"
His words cut out from beneath him as he stepped away from the stage to where the next performers should have been lining up. One of the members of comedy troupe currently on stage had just missed his cue and punchline. Instead the manager found the troupe member, dressed as the proverbial zebra, standing over the lifeless body of a makeup girl. In his hand/hoof he held a knife covered in blood.
"Holy hell," the manager exclaimed, "it really was the Zebra!"
