When I was at college in Leeds in the '80s, I remember this pearl of wisdon scrawled on the wall of the Hall launderette:
'There's nothing as overrated as a bad f**k, nor anything as underrated as a good s**t.'
Sadly, the name of this philosopher is lost to posterity, but since we're in contemplative mood, I suggest we turn our thoughts to this assertion....
...can't say I argue with it.
