Sometimes, there’s nothing better than a gratuitously geeky joke to raise a smile. Today’s XKCD certainly provides just that.
As if the setup, above, wasn’t funny enough, the punchline is hidden in XKCD’s al-text:
<A>: Like </a>this.
If that makes you laugh, great! If it riles you, sorry! And if you don’t get it, learn some HTML. [XKCD]
