Comic Strip Search Engine

Looking for a little humor to lighten the mood or perhaps make a point? Check out OhNoRobot, a search engine for the text in online comic strips.
A couple of caveats courtesy of LibrarianInBlack (from whom I discovered OhNoRobot):
– A lot of the more mainstream online comics aren’t included. There are about 232 comics that are indexed.
– Many of the comics included are extremely alternative–and perhaps not always safe for work. Reader beware.
On a related note, Unshelved, a comic about libraries had a bit about library blogs this month (See Dec 5-10, 2005). Unshelved doesn’t seem to be indexed by OhNoRobot.
