Three men were using the urinals in a public restroom in the UK.
The first man finished relieving himself, zipped up, strolled to
the sinks and proceeded to wash his hands, using plenty of soap and
water and doing a splendidly thorough job.
As he was drying his hands (with lots of paper towels), he
loftily announced to no one in particular "At Oxford, I learned to
be clean and sanitary." The man then left the bathroom in a cloud
of self-satisfaction.
The second gent zipped up, marched briskly to the sinks, and
scrubbed his hands with much less soap and water than the first
man, doing a splendidly thorough job nonetheless. As he was drying
his hands (with only one paper towel), he severely announced to no
one in particular," At Cambridge, I learned to be clean and
sanitary, but I ALSO learned to be thrifty and environmentally
conscious." He then strode from the bathroom with a purposeful
air.
The third man finished relieving himself, zipped up, and ambled
past the sinks to the door, muttering to himself, "In Australia, we
learn not to piss on our hands."
