A very tired nurse walked into a bank, totally exhausted after an 18-hour shift.

Preparing to write a cheque, she pulled a rectal thermometer out of her purse and tried to write with it.

When she realised her mistake, she looked at the flabbergasted teller and, without missing a beat, said:

‘Well, that’s great! That’s just great! Some arsehole’s got my pen.”

Thanks to Tom the teller for this weeks tit-bit.
