Nurse
 

A nurse walks into a bank. Preparing to write a check, she pulls a rectal thermometer out of

her purse and tries to write with it. She looks at the flabbergasted teller and without missing a beat says,

"Well, that's great..........that's really great.......... some *********'s got my pen."

You know how to spot the head nurse?

She's got the dirty knees...
