blonde girl where i worked years ago walked past my workstation going ...."dum de dum dum dum".
I said "talkin bout yourself again."
Brought the house down.
And then there was the joke where the woman was asked 'How many 'D's in "Raiders of the Lost Ark"?'
She paused for a bit, then said '47'. 'Dee da dee dee, dee da dee, de da dee dee...'
Not bad, took me a second...
