The jargon-filled script:

Gravity should integrate gracefully with the standard model: eletromagnetism, the weak and the strong force. 

Einstein, Feynman, Hawking, and folks with more talent than myself, have failed in this quest, so I must cheat in a simple way.

Physicists work with tensors in 4 dimensional spacetime

There is only one set of rules to work with these tensors, the rules of tensor calculus.

Nature may have deceived us for more than two centuries because she has multiple ways to multiply.

Gravity is the universal attractive force.

Gravity needs a product that only has plus signs, no minuses.

By using several types of 4D products in the Lagrangian on the back of the shirt, I can use the Euler-Lagrange equations to get the unified gravity and standard model equations on the front of the shirt.
