I do lots of random google searches these days, wondering who or what something is (although admittedly half the time I'm just looking for previous work from actors on IMDB, or I'm using wikipedia). I guess everyone does, these days, leading to the eternal question posed there.
I can't guess what this comic is referring to. The "context"--the surrounding comics, though they don't seem relevant--is here. (My best guess is that the whole thing is made-up, with nothing specific in mind, but that doesn't seem like the author.)
I also can't figure out what the pun in this comic would have been. (context)
