Zimbabwean Eggs

Two Zimbabweans are on a bicycle about 15 miles outside of Manchester, UK.  One of the bike's tires goes flat and they start hitching a lift back into town.

A friendly trucker stops to see if he can help, and the Zimbabweans ask him for a ride.  He tells them there is no room in the trailer, as he is carrying 20,000 bowling walls.  The Zimbabweans put it to the driver that if they can manage to fit into the back with their bike, will he take them back into town.  He agrees.

They manage to squeeze themselves and the bike into the back and the driver shuts the doors and gets on his way.  

By this time he is rally late and so puts the hammer down and sure enough, a blond cop pulls him over for speeding.  The lady officer askes the driver what he is carrying, to which the driver jokingly replies "Zimabawean eggs."

The blond lady cop obviously doesn't believe this and asks to take a look in the trailer.  She opens the back door and quickly shuts it and locks it.

She gets onto her radio and calls for immediate backup from as many officers as possible plus the Swat Team.  The dispatcher asks what emergency she has that requires so many officers and she says "I've got a Tractor-Trailer stopped with 20 000 Zimbabwean eggs in it.  Two have hatched and they've already managed to steal a bicycle!"
