The World of Star Trek recalls a practical joke, involving Gene Roddenberry that was played on Steve Carabatsos. According to Roddenberry: "Matt Jefferies got hold of a weather balloon and we got some helium. We poured about a pint of cheap perfume in it and then we put the balloon in his office and blew it up so it completely filled his office and pushed the door closed against it and waited for Steve to come to work. He opened the door and walked right into this thing and we knew the only way he could get into his office was to break it, and breaking all the helium and air mixed with perfume would make his office smell like a Turkish whorehouse for a month, and indeed, that's what happened."
