Two illegal aliens are on bikes, having just crossed the border. One of the bike's tires goes flat and they start trying to hitch a ride.
A friendly trucker stops to see if he can help and they ask him for a ride. He tells them he has no room in the Trailer as it is full of eggs.
They ask the driver if they can manage to fit into the trailer with their bikes, if he will he take them to the next town, and he agrees. They manage to squeeze themselves and their bike into the back and the driver shuts the doors and gets on his way.
By this time he is really late and so puts the hammer down. But 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 "alien ‘n 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 alien eggs in it... two have hatched and they've managed to steal a bike already. I need help!"
