A random, non-exhaustive list of xkcd’s that were highly effective in making me think ( and laugh! :P)

Ayn Random is pretty much objective.

The Monty Hall is not a difficult problem at all.

What if headlines were written to garner more clicks?

What do you want to do with life?
The sweetest illogical logic in life - Love.
You know this if you have ever contributed to the wikipedia.
Terribly Tasty.
String thoery and science.
Sounds more like an Armageddon.

Prometheus!

Analogy.
Natural Selection.
A Green Flash?

T.I. will always be hated.

Definitely the sweetest among the whole of xkcd.
