In their review of Magic Whistle: Bigger, Larger and Bigger! the San Antonio Express-News wrote that Henderson's "crude, blobby little scratchings are some of the funniest junk being turned out." Henderson was nominated for the Harvey Award's Special Award for Humor every year from 1999–2004.

Henderson was born in Woodstock, New York. He attended Boiceville, New York's Onteora High School, graduating in 1987, and the School of Visual Arts in New York City, where he graduated in 1991.

Henderson has been self-publishing xeroxed minicomics since 1980. In the mid-to-late 1980s he drew and published a comic called Captain Spaz with his friend Bobby Weiss. The series ended in 1988 as he was busy in college. In college, he drew a series of minicomics featuring a character known as Monroe Simmons. In 1993 he began self-publishing his best-known title, The Magic Whistle, now published by Alternative Comics. Also in 1993 he began the wordless comic strip "Scene but Not Heard," starring a pink man and a red bear, in Nickelodeon Magazine. It was the magazine's longest-running comic strip. A collection is due out in 2010.
