XKCD... What Does That Even Mean??

I'm only partially sure as to the meaning of the site's name, but that doesn't keep me from enjoying the stick-figure comic strips it posts every Monday, Wednesday, and Friday. I will provide a disclaimer here: it is occasionally irreverent, occasionally inappropriate, but regularly hilarious. I would recommend for adults, by and large.
Some of their strips are nerdy by nature, implying they were written by a geek of significant intelligence. Others are about God or religion; those can be funny but I take them with a grain of salt. I am new myself to keeping up with this site and haven't perused all the old strips yet. But still, I encourage anyone interested to visit XKCD.com . I'll try to post a few funny examples for reference sake.
