Every few minutes, someone interrupts the doctor:

“Can you look at this rash?”

“My back’s been killing me …”

“Does this mole look weird?”

After almost an hour of free check-ups, the doctor sighs and asks the lawyer:

“How do you deal with people asking for free legal advice outside of work?”

The lawyer smirks: “Simple. I give them advice … then I mail them a bill.”

The doctor blinks. “You’re joking.”

“Not even a little.”

Inspired (and mildly vengeful), the doctor decides to try it.

The next day, he writes up bills for everyone who bugged him at the party.

As he heads to the mailbox to send them off…

He finds something already waiting for him.

A bill.

From the lawyer.
