I’ve been staring at this strip all day, pasted it on my wall, read all the strips from its parent webcomic (xkcd) — and still it dazzles me. It has got to be among the best I’ve ever read. Quirky, sexy, naive, upbeat — makes me happy every time.
Oh boy, I really love this strip. I’m going to be pasting it everywhere… :))
Dreams comes close after it; Pong, Donald Knuth, M.C. Hammer Slide, Words that end in gry, and Moral Relativity are also keepers; and both Escher Bracelet and Sudoku are almost single-panel-ly perfect in their simplicity.
