Russell's Teapot is a philosophical argument that reflects on the difficulty of trying to prove a negative. It involves a hypothetical teapot orbiting a heavenly body, whose existence hasn't been proven. It is very often used in atheistic arguments. Russell's Teapot is an analogy which Bertrand Russell devised "to illustrate that the philosophic burden of proof lies upon a person making unfalsifiable claims, rather than shifting the burden of disproof to others."
"He wrote that if he were to assert, without offering proof, that a teapot orbits the Sun somewhere in space between the Earth and Mars, he could not expect anyone to believe him solely because his assertion could not be proven wrong." (Wikipedia)
Cueball is trying to settle the teapot argument by actually launching a teapot into space via a crowdfunding campaign.
The title-text refers to Bertrand Russell's Barber Paradox. In this paradox, it is stated "one who shaves all those, and those only, who do not shave themselves.". However, this is impossible, because if the barber does not shave himself, then the statement is false (because he is a man the barber does not shave). If the barber shaves himself, then the barber himself is one man who shaves himself and that the barber shaves.
Cueball is standing in front of a blueprint labeled "CubeSat-Based Design", containing a satellite with a teapot in the top.
Below the comic box:
"I'm crowdfunding a project to launch a teapot into orbit around the sun to settle the Russell thing once and for all."
Unfortunately, NASA regulations state that Bertrand Russell-related payloads can only be launched within launch vehicles which do not launch themselves.
