many clowns in a small car is very funny, but zero clowns in a big car is not at all funny. one could extrapolate from this data that a normal amount of clowns in a normal sized car is the normal amount of funny, but it's not. this is the clown paradox.
hypothesis: humor is perhaps not about the quantity of clowns, but the volume.
further research is needed.
To make this more difficult, one singular small clown in an extremely large car is funny again.
Hypothesis: humor can be measured by standard deviation from the mean density as measured by clowns per volume inside of a car
