As for it being standard operating procedure, I don't know whether it is or
not. who cares?
It's true, located somewhere near our colons (which explains the toilet
humour), the humour gland is missing in several
"improved" "civilisations", leading to a greater level of ***retention
among the "better" humans among us.
Good news though! There have been several attempts to stop this
ridiculous behaviour and soon "joke" will only appear in dictionaries
(suitably annotated ones of course which are unavailable to children and
the rest of society which is unable to make up their own minds).
God forbid that people should be expected to laugh at themselves.
Who's wondering if you complained about the Anna Kornikova fans as well?
