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!'
