It turns out that there's a scientific and logical explanation for why people (mostly men) spend so much time in pubs and only get home in the early hours of the morning. The reasons for this odd behavior are based on Einstein's famous Relativity Theory. It works like this: -
It is a well known fact that the more you drink, the faster you move.
After about 8 beers, you're moving at close to the speed of light, and this is where Einstein enters the picture.
According to his Relativity Theory, any body moving at, or close to the speed of light, undergoes Time Dilation, i.e. time for you in the pub passes slower than for an observer outside the pub. Complicated calculations have shown that the pub becomes a type of time machine: - for every half-hour spent inside the pub, something like two hours pass outside the pub.
A typical situation is "OK guys, it's 8 Oclock; I'm going home early to surprise the family!" However, the moment this person steps outside the pub, the time travel effect is negated by negative radiation from the environment, and he/she then goes: "WTF - why is it so quiet? Holy shit! It's half past one! WHAT HAPPENED?" ...and the answer, of course, is Time Dilation!
I've tried to explain this to outside observers, but so far nobody (except fellow time travellers) has been able or willing to understand the sound scientific basis of this phenomenon. Please forward this to all your time traveller buddies - maybe we can prove this theory by sheer, overwhelming force of numbers.
