Geller's law of gravity: If something is on the floor it cannot fall down.

Geller's law of interpersonal physics: If you throw a stone in the water the waves will make you wet.

My wonderful professor, Stuart Shapiro, taught me that "If you did not write it down, it did not happen." I feel this rule should be extended.

Geller's first rule of epistemological ontology: If you did not take a picture of it, it did not happen.

Geller's second rule of epistemological ontology: If you took a picture of it and did not post it on facebook/instagram/etc. it still did not happen.

Geller's third rule of epistemological ontology: If you did not take a video of it and post it on YouTube it did not happen.
