Interesting concept, perhaps you could include other equations like the calculations of Ek = 0.5mv^2. Blow the whole thing up to the egg thinking of the force of it hitting the ground, etc etc. Massive Physics Equations ftw!
yeah i usually use 's' or 'x' for distance in my equation. and why is it thinking that. is he working out how high he was when he was dropped? other then that i like it. i like it big also, you get your moneys worth.
I like it - smaller on the shirt would be good.
Broken egg on the back, also good!
The variable choice is individual - I'd use z=vt+gt^2/2, myself.
IMHO, it'd be funnier with the equation for force, or the equation solved for time, or yield strength of a curved material, or even final velocity.
(Of course, I'm an engineer, so my humour might be a bit particular!) I just see those as funnier than distance... Not sure why...
