If you're above average intelligence and have any appreciation for comedy, check out the comic strips at xkcd.com, some are hilarious. You will appreciate 50% more of the jokes if you have decent understanding of science or mathematics
Any who, here are 5 goodies. I loved Jurassic park so the first 3 comics make reference to this, and they're gold, maybe I watched Jurassic park too many times as a child. Hover your mouse over the comic strip to see a the second punch lime/comment.
