The New Hearing Aid

A partially deaf gentleman was extolling the virtues of his new hearing aid.

- It's marvelous - he enthused to a friend.

- Since I acquired it I can hear the birds chirping on the hearth. I can also hear clearly a conversation being held in an apartment a full block away!

- You don't say - said his friend.

- What kind is it?

The proud owner consulted his wristwatch and answered:

- Twenty minutes after two.
