When electrons get excited, they jump electron energy levels (n=1 to 2, 3, 4, etc.) The only way they can come back down the energy levels is to release energy in the form of photons of light.
Likewise, when a male becomes excited (and thus has an erection), the only way to make the penis come back down energy levels is to release energy in the form of sperm.
Hence, the Erection-Electron Theory explains the correlation between scientific theory and everyday practices.
Wow! The Erection-Electron Theory explains everything that is wrong in the world!
