Bert is Evil is the name of a widely mirrored web site, founded by Dino Ignacio, which featured Bert, a character on the American children's television program Sesame Street. In 1998 Dino Ignacio, Wout J Reinders and Jasper Hulshoff Pol accepted the Webby Award and the People's Voice Award for Best Weird Website at the Palace of Fine Arts auditorium in San Francisco.
The website featured manipulated images of the puppet consorting with nefarious figures including Adolf Hitler, Osama bin Laden, and Jerry Springer, and present at tragedies such as the JFK assassination, humorously offered as "proof" that Bert was no mere innocent children's television character. The "Evil Bert" phenomenon was picked up by other humorists, who created their own images linking Bert to current and historical atrocities.
In the summer of 1998, due to the website's immense cult popularity, it became too cost prohibitive for Ignacio to continue running. Instead of shutting the site down, he offered to allow anyone who was willing to mirror his original website the opportunity to host it. As a result dozens of mirrors appeared, increasing the website's popularity and visibility.
