Physics comic about refuting beliefs in gravity and thermodynamics

[QuantumCosmo]

Hi,

I once read a physics comic that went something like this:

two people, one was floating in the air and told the other "I have refuted my belief in gravity"

... I think he then proceeds to refute several other things and they all vanish/dont work for him anymore...

(I think there was a part where he jumped into a volcano und didnt get burned because he knew thermodynamics)

and in the end, the other guy asks him "what happens if you refute your belief in god" "nothing"

I don't remember where I read that comic, but I really liked it and was planning to pin it up on our office door, so it would be really nice if someone knows it and can post a link.

Thank you!

Maybe something to do with the theory of Intelligent Falling?

I remember the comic, and it was unrelated to that.
I just don't know where I saw it :(. xkcd was my first guess, but a my search there was not successful.

Abstruse goose perhaps?
