Three generations of prostitutes - a daughter, mother and grandmother - are all living together in the same house.
One morning the daughter comes home completely exhausted after a hard night's work.
She turns to her mother and grandmother.
"You know, times are really getting hard." she says.
"I just had to give some bloke a blow job for half an hour and all I got for it was a lousy ten quid".
Her mother replies,
"You should consider yourself lucky young lady - in my day all I got was two and sixpence".
The grandmother looks at both of them and says,
"You two should both consider yourselves lucky -- in my day we were happy just to have meat in our mouths and something warm in our bellies."
