A teacher is talking to her class full of infants "If your mother was a bird, what sort would she be?" she asks the children
The first child says - "If my mummy was a bird, she'd be a dove",
"That's nice" said the teacher, "why's that?"
Because she's beautiful and pure and reminds me of a dove" says the little boy
"If my mummy was a bird, she'd be a stork" says the second boy,
"Oh and why's that?" says the teacher
"Because she's tall and elegant and reminds me of a stork" says the boy
"If my mummy was a bird she'd be a thrush" says the third boy
"Why's that?" says the teacher
"Because she's an irritating c**t!"
