A guy walks into a post office one day to see a middle-aged, balding man standing at the counter methodically placing "Love" stamps on bright pink envelopes with hearts all over them. He then takes out a perfume bottle and starts spraying scent all over them. His curiosity gets the better of him and he goes up to the balding man and asks him what he's doing.
"I'm sending out 1,000 Valentine's Day cards signed, 'Guess who?'"

"But why?" asks the man.

"I'm a divorce lawyer."

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 takes the bags and rips them apart; he empties them out and finds nothing in them but sand.

He detains Juan overnight and has the sand analyzed, only to discover that there is nothing but pure sand in the bags.

The guard releases Juan, puts the sand into new bags, hefts them onto the man''s shoulders, and lets him cross the border.

A week later, the same thing happens. The guard asks, "What have you got?"

"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 if 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..... I can't sleep. Just between you and me, what are you smuggling?"

Juan sips his beer and says, "Bicycles."

As a senior citizen was driving down the freeway, his cell phone rang.

Answering, he heard his wife's voice urgently warning him, "Herman, I just heard on the news that there''s a car going the wrong way on Route 280. Please be careful!"

"It's not just one car," said Herman, "It's hundreds of them!"
