An banker, a cowboy and Dr. Bob were setting at a bar and each ordered a mug of beer. Well each mug had a fly in it.
The banker told the bar tender he wanted a beer without the fly.
The cowboy just flipped the fly out of his beer and drank it down.
Well Dr. Bob reached into his beer and grabbed the fly by the wing and ...started shaking it shouting, "spit it out, spit it out!"
