Penny

Yo Mama so stupid if you gave her a penny for her thoughts, you'd get change.
Why don't crabs donate to charity?
They're shellfish penny pinchers.
Why did the sailor throw a penny into the whale’s mouth?
The sailor thought he was was a wishing whale!
Yo Mama so short she can sit on a penny and swing her legs.
There was a young woman named Jenny
Whose limericks were not worth a penny.
Oh, the rhyme was all right,
And the meter was tight,
But whenever she tried to write any,
She always wrote one line too many!
What did the penny say to the other penny? We make perfect cents.
What is brown and has a head and a tail but no legs? A penny.
