A very tired nurse walks into a bank,
Totally exhausted after an 18-hour shift.
Preparing to write a cheque
She pulls a rectal thermometer out of her purse
And tries to write with it...
When she realises her mistake,
She looks at the flabbergasted teller
And without missing a beat, she says:
'Well, that's great....that's just great....
Some arsehole's got my pen!'
