Reverse Bel-Air from xkcd

I'm very new to the term webcomic, let alone the phenomenon itself. Following on from my Garfield minus Garfield appraisal here, suffice to say that xkcd, 'A Webcomic if romance, sarcasm, math(s) and language', has excelled itself with this strip. I'd file this under romance and sarcasm. Easy on the math(s).
