Bert is a fictional character, a Muppet on the Public Broadcasting Service's long-running children's television show, Sesame Street.
Bert was originally performed by Frank Oz. Since 2001, Muppeteer Eric Jacobson has been phased in as Bert's primary performer.
He and his friend and roommate Ernie form a comic duo that is one of the program's centerpieces, with Bert acting the world-weary foil to Ernie's naïve trouble-maker. A characteristic physical feature of Bert is his monobrow.
Bert has a pet pigeon named Bernice, and he created a dance called "Doin' the Pigeon".
A typical "Bert and Ernie" skit has Ernie coming up with a hare-brained idea and Bert attempting to talk him out of it, ending with Bert completely losing his temper and Ernie remaining oblivious to his own bad idea. Bert has a twin brother, Bart, a nephew, Brad, and an Aunt Matilda. Brad (presumed to be played by Richard Hunt) had a voice like Beaker, but slightly deeper, and while he still made baby-like noises, he was able to talk. Ernie brought a toy shark with him in one skit; Brad was scared by it, not realising it was a toy. Bart looks exactly like Bert - Ernie once mistook Bart for Bert - but Bart wears a suit and fedora and is a salesman ("Bart's the name and selling's my game!").
The age of Bert and Ernie is regularly discussed on forums. Nothing official has ever been said, but most consider the duo adults, as they do not appear to be highly dependent on others. Helping suggestions of the characters being young is a comment by Sesame Street Live performer Taylor Morgan. Morgan said to the Macon Telegraph that "I just kind of try to think like a 6-year-old or 7-year-old, because that's how old Bert is." *
Ernie and Bert share an apartment in the basement of 123 Sesame Street. Although they sleep in separate beds, this has led to the occasional suggestion that they are representations of gay lovers. Sesame Workshop, the corporation that owns the show and the characters, denies this and is occasionally compelled to point out that Bert and Ernie are made from cloth and other materials, and have no sexuality whatsoever. In the satirical musical Avenue Q, the character of Rod is based on Bert and is a closeted homosexual.
A humor website "Bert is Evil" hosted digitally manipulated images and satiric articles as "evidence" of Bert being evil. The site depicted the Muppet consorting with Adolf Hitler and the Ku Klux Klan and present at the Hindenburg disaster. The site drew worldwide attention in 2001 when a photo of a Bangladeshi street protest was distributed by the Reuters news agency; the photo included a protest sign that depicted Bert with Osama bin Laden, an image that had been inadvertently placed there by the owner of a poster shop in Dhaka.* Although the Bert-with-Osama image never appeared on "Bert is Evil," owner Dino Ignacio took the site off-line anyway.
The song and dance "Doin' the Pigeon" inspired an end zone dance by San Francisco 49ers defensive back Merton Hanks.
According to Henson, Bert and Ernie were not named after characters of the same name from the classic Christmas movie It's A Wonderful Life.
