Juan comes up to the Mexican border on his bicycle. He's got two large bags over his shoulders. The guard stops him and says, "What's in the bags?"
"Sand," answered Juan.
The guard says, "We'll just see about that. Get off the bike." The guard detains Juan overnight and has the sand analyzed, only to discover that there is nothing but pure sand in the bags. He releases Juan and lets him cross the border.
A week later, the same thing happens. The guard asks, "What's in the bags?"
"Sand," says Juan.
The guard does his thorough examination and discovers that the bags contain nothing but sand. He gives the sand back to Juan, and Juan crosses the border on his bicycle.
This sequence of events is repeated every day for three years. Finally, Juan doesn't show up one day and the guard meets him in a Cantina in Mexico.
"Hey, Buddy," says the guard, "I know you are smuggling something. It's driving me crazy. It's all I think about...Just between you and me, what are you smuggling?"
An Indian gentleman was trying to smuggle an elephant through customs, the elephant had a slice of bread in each ear, the officer says ''Good morning sir, anything to declare?'' the man says ''oh no, nothing at all sir''....''well what about that then?'' he said pointing to the elephant... he says ''please sir, whatever I put in my sandwiches has nothing to do with you!''
Being a Customs and Immigration Officer at an airport is a really boring job. Day in, day out, scanning endless lines of tourists looking for anything unusual... these guys deserve our sympathy and support. So why not put a smile on their faces with this hilarious practical joke? Next time you're flying anywhere, simply wrap your sandwiches in tin foil and tape them around your chest under your clothes. That'll liven up their day!
