Since it is much more likely to have a girlfriend, we can suppose that in a random system (one without social standards, fear or psychological complexes) nearly everybody would have a girlfriend. Since this is not the case and we don’t want to violate the second law of thermodynamics we can suppose that people without girlfriends do more work in order to go to a state of lower entropy.
This is one of the weirdest conclusions I have ever heard and I love it! It also contradicts the Drake-Backus equation in the most humorous way. Thermodynamics rock!
