Mexican Eggs

Two Mexicans are on a bike along U.S. 52 about 15 miles

 outside of Lafayette, LA.
 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
 Mexicans ask him for a  ride.
 He tells them he has no room in the trailer as he is
 carrying 20,000 bowling balls.

The Mexicans 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, and he agrees.

 

They manage to
 squeeze themselves and their bike into the back and the drivern shuts the doors
 and gets on his way
  
By this time he is really late and so puts the hammer down. 

 Sure enough "Old Smokey" pulls him over for speeding. 

 

The good officer asks the driver what he is carrying to which the  

 driver jokingly replies "Mexican eggs".

The Cop obviously doesn't believe this so wants to take a look in the trailer. 

 He opens the back door and quickly shuts it and locks it. 
 He gets on his radio and calls for immediate backup from as many officers
 as possible plus the Swat Team.

The dispatcher asks what emergency he has that requires so many officers. 

 "I've got a Tractor-Trailer stopped with 20,000 Mexican eggs in it...

 two have hatched and they've managed to steal a bicycle already."
