Talk:1578: Squirrelphone

Could it be a reference to this? http://web.media.mit.edu/~stefanm/phd/cellularsquirrel/

What about the old "Bananaphone" pun?

Sometimes I wonder if the joke is to make ExplainXKCD squirm.

^ Not really. Those like me who used SquirrelMail had a laugh. Mostly every XKCD joke is incomprehensible to people not familiar with the subject of the joke.
