A Parrot joke

An old lady buys a pair of parrots, but cannot identify their sexes.

She spends weeks staring at the cage and, eventually, catches them doing what comes naturally.

To make sure she doesn't get them mixed up again, she puts a little white collar around the male parrot's neck.

Later, the local priest visits the old lady.

The male parrot takes one look at the father's collar and says,

"I see she caught you at it, too !"
