Sheldon by Dave Kellett
by GoComicsSheldon is a strange strip with geeky characters, all-ages storylines, and pop culture nerdiness. Twice nominated for the Eisner Awards' "Best Humor" category, Sheldon centers around a wonderfully odd little family: A boy, his duck and the grandfather who raises them both. The strip is famous for venturing away from the main cast and into stand-alone comics and storylines.
