The first is xkcd, who is apparently trying to give us all headaches by turning every comic into 3D looking:

Dazzled, all the student could think of was, “I don’t know”.
The professor, equally baffled, replied, “Seriously? Come on. It’s common knowledge!”
Heisenberg: “You must know too much about their momentum.”
In the Futurama episode The Prisoner of Benda Ken Keeler displays and proves an original theorem in order to advance the plot of the episode.
In the episode, the professor invents a machine that swaps the minds
of two people, but the swap can only happen once for a given pair of
people. The problem posed is:
Given a group of people with swapped minds (with some swapped several times), is it possible to return each mind to their original bodies?
What are necessary conditions?
The theorem provided by Futurama is now named the “Futurama Theorem” and has its own entry on wikipedia! The theorem states that, no matter how many individuals have swapped minds with one another, everyone’s mind can be returned to his or her original body by using only two additional individuals (who have yet to swap minds with anyone).
One lawyer says, “If they call themselves 99 Cents Only, it should be 99 cents.”
However, the CEO claims that: “we changed all the signs, we have a large poster in the window of every store explaining the increase, we put it in our ads in the newspaper, we put it on the radio…”
That 0.99 cent increase was projected to bring in an additional $12 million in revenue annually!!
