*** - 'R.N. tired' - after long hard 12 hour shift - ***
 

------------------------------------------------------------

A very tired nurse walks into a bank,

Totally exhausted after a twelve-hour shift.

Preparing to write a cheque,

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!'
