Randall Munroe is the creator of XKCD (xkcd.com), what he calls, “A webcomic of romance, sarcasm, math, and language.” The strip above is reprinted with permission. You can see more at the URL linked near the beginning of this paragraph.

I provide, however, Randall’s standard disclaimer, as posted on his website:

“Warning: this comic occasionally contains strong language (which may be unsuitable for children), unusual humor (which may be unsuitable for adults), and advanced mathematics (which may be unsuitable for liberal-arts majors).”

Enjoy!
