Remember that one 'Calvin & Hobbes' strip when Calvin said something really funny in class but he was imagining himself in a war? Was it a war? Maybe he was in space. We just remember it had something to do with a book report. 

Love 'Calvin & Hobbes' and demand the entire comic collection be at your fingertips at all times? Created by Michael Yingling, the 'Calvin & Hobbes' search engine has every C&H strip available by just searching any term or phrase you kind-of remember from an original strip.

This should kill a couple days of time. Ironically, here's the strip that appears if you search "killing time."
