Shannon Wheeler is an American cartoonist best known for creating the satirical superhero Too Much Coffee Man, and as a cartoonist for The New Yorker. He started cartooning while at UC Berkeley, publishing his daily gag cartoons "Calaboose" and then "Tooth and Justice" in The Daily Californian. He moved to Austin, Texas and created the satirical superhero Too Much Coffee Man as the star of a weekly comic strip in 1990. He eventually published the character in a series of self-published zines, comic books, magazines, and webcomics for a number of years, culminating in 2006 with the Too Much Coffee Man Opera (in one act), followed by Too Much Coffee Man Opera, The Refill (in two acts) in 2008. Wheeler's weekly strip Postage Stamp Funnies appeared in the satirical newspaper The Onion until 2009, when he began contributing to The New Yorker magazine.[3] In 2010, Wheeler published a collection of his cartoons rejected by The New Yorker called I Thought You Would Be Funnier.
