The Snoid, occasionally referred to as Mr. Snoid, is an American underground comix character created by Robert Crumb in the mid-1960s. A diminutive sex fiend and irritating presence, the Snoid often appears with other Crumb characters, particularly Angelfood McSpade, Mr. Natural, and Crumb's own self-caricature.

Yarrowstalks was an underground newspaper, primarily based in Philadelphia, Pennsylvania, that published 12 issues from 1967 to 1975. It is notable for being the first publication to publish the comix of underground cartoonist Robert Crumb. In addition to Crumb, other notable contributors to Yarrowstalks included Timothy Leary and the editor/publisher Brian Zahn.
