Bob Viking:
There's always someone with a bigger dick!
There is in fact a Law of Swinging Dicks, which goes something like: "When two or more swinging dicks are gathered together in one place for the purpose of achieving cooperative ends, the amount of cooperation actually achieved is inversely proportional to the ambient level of testosterone".
Empirical evidence of this law exists in all parliaments, and clearly at some public events attended by retired officers...like funerals.
