Twenty-year-old Walter Morrison is stupid.

He was unloading a cargo plane at Sky Harbor Airport in Phoenix when he stashed a package in his shirt. He originally assumed it contained money, but he was wrong. Apparently unaware that diamonds are forever and expensive, he traded the $160,000 jewel for a $20 bag of weed.

How stupid can one person be? You would think he would at least look at what he stole before he sold it.

I guess they say one man's treasure is another man's trash.
