You're sitting in your cube and all is calm, and you're concentrating on something important.  Suddenly you hear a strange noise...

*kaching* *kaching* *kaching*

You turn around and look out into the cube hall expecting to feel a light breeze wash over your face as a tumbleweed blows by.  Instead you see a man walk by who must have $8.00 in change in his pocket, and probably more keys stuffed in his pocket than the building custodian.  And then for the next hour, all you can hear in your head is "I've got change that jingle jangle jingles."

It's the male equivalent of the thwacker... and it's just as evil.
