If posting a comic that uses the "F" word will change your opinion of me. . . I'm sorry I disappointed you. But I'm not apologizing, because real life has the "F" word in it, too, sometimes. (And nudity -- parents are STRONGLY cautioned that some parts of real life may not be suitable for viewing by small children, families, or the discernment-impaired.)
XKCD is a comic my brother-in-law showed me. It varies from way over my head, to extremely nerdy, to awesome, and from "I know I got it but it really wasn't funny" to snarky, to drop-dead-hilarious. Here's a recent issue. I like it.
As the comic homepage itself says:
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).
