I recently went to one of the hospitals.

Operational, wait with the surgeon until the patient (man) is prepared for the leg prothesis.

Nurse: work with your fist... * insert an needle *... you can press
Surgeon: What did she say? Can you give birth?
I: Yes, doctor, he’ll be born here and we’ll get the Nobel Prize and a million backs from above.
Surgeon: Oh, and a p$d from the boss!
