I hate missing the joke

When I don’t get geek humor, rather than feel good that maybe I’m not as far gone into geekery as sometimes seems to be case, I feel stupid.  Well, I guess it depends on what kind of joke it is I’m not getting.  Today’s XKCD is an example of the kind of geek humor that makes me feel dumb.  My education didn’t include whatever the hell makes this funny.

Things I do find funny?  I’m so glad you asked!

Sign I think I want to post around my neighborhood (also from The Daily What):

Beyond those things, nothing is funny.  Nothing in the world.  Ever.  And ever.
