To announce the premier of "Animaniacs" in September 1993, it was decided to place an inflated-balloon replica of Yakko Warner atop the water tower at the Warner Bros. studio lot in Burbank. This seemed like a great idea at the time. Unfortunately, no one clued in Bob Daly, who ran the studio. When Bob pulled up in his car that day and saw the balloon-creature sitting on top of the tower, he thought his studio was under attack by some sort of mutant Mickey Mouse.
The balloon figure of Yakko sat on the tower for less than 12 hours. Paul Rugg snapped this photo, which may be the only documentation of this strange day in studio history.
