Tired nurse.
 

A tired nurse!


A very tired nurse walks into a bank.

Totally exhausted after an 18-hour shift.
Preparing to write a check, she pulls a rectal thermometer out of her
purse and tries to write with it.
When she realizes her mistake, she looks at the flabbergasted teller
and without missing a beat, she says:
'Well, that's great....that's just great.... some asshole's got my pen!'
