Cuckoo for Koi

Some thieves appear to fish to diamonds. Dressed in khakis and white shirts, a group of cunning con artists showed up at a business park and helped themselves to a pond full of koi - one can fetch up to $2,000 on the black market. The thieves said they were there to do "fish maintenance" and even presented business cards. They scooped up the "sick" fish, packed them in coolers and drove off. It was only after the fourth visit to the pond that management realized it had not hired a "fish maintenance" company. By then, the thieves had already made off with 400 koi.

Traffic-Stop Birth

On Wednesday, police officers were making a routine traffic stop in Milwaukee, Wis., when they realized that one of the passengers was giving birth. The mother was in labor and the father was speeding to the hospital. The officers jumped into action and called for medical support but baby Isabella - at 6 pounds, 5 ounces - was born right there on the side of the road.

Other occupations Jagger had considered included a politician and a journalist. We think he made the right choice.
