The Fart Artist.

As an entertainer, Joseph Pujol had a unique talent:

On stage, dressed in a fine red coat and black britches, Le Pétomane began each performance by explained to his audience that his emissions were odorless. After reassuring the masses, he would launch into his act. He would start with a comedy series of what he called ‘fart impressions’. He would emit a tiny toot, label it as the fart of a ‘new bride’, then flap a thunderous emission and label it as the same bride a week into the marriage. He did impressions of famous people, squeezed out a ten-second long squeaker, and then blew out candles using nothing by the gases emitted from his posterior.

For his finale Le Pétomane inserted a rubber tube into his anus, attached an ocarina to the end of the hose, and played popular tunes while inviting the audience to sing along.
