An old but fresh lawyer (because from being a lawyer you will not get a pension, you die directly), is hearing to well. He goes to the doctor, who advices him to get an ultramodern deaf aid, very discrete.

Over a month the lawyer comes back for a check.
The doctor:
“The deaf aid makes his job, your hearing is perfect. I think your family is very glad that you can hear again.”
“Oh… I didn’t tell them yet, I just stay and listen. I’ve changed my testament three times until now.”
