My mum is a retired care worker,
she spent many years wiping old folks arses,
for low wages, low status, and few thanks..

She's now 87 and incontinent, wearing adult nappies,
if she can remember, or be persuaded to put them on in time.

Bum and poo jokes are an essential part of our daily phone conversations,
she finds the subject hilarious, it cheers her up.
That's the dark humour of folks who work at the arse end of society,
care workers, paramedics, etc..

One bonus of her dementia is we can say the same poo jokes day after day,
and she always finds the old punchlines fresh and funny...
