Kind of Doctor

After making love, the woman said to the man:

- So, you're a doctor?

- That's right - replied the doctor smugly.

- Betcha don't know what kind of doctor.

- Ummm... I'd say that you're an anesthesiologist.

- Yep, that's right! Good guess! How did you know? - asked the guy.

- Because throughout the entire procedure, I didn't feel a thing.
