Seen this yet?
TV Tropes and
Cracked.com. Probably the only two websites I've ever sat there with 50+ tabs open in.
I actually kept myself awake in San Francisco all night so that I would be up to catch a plane at 5am by sitting there on TV Tropes.
And in opening the websites to get their addresses, I suddenly have 8 more tabs open.
DAMN YOU, XKCD! HOW DO YOU KNOW?!?
