They’ve got drinking water with quite a bite to it in Jamestown, N.D.

Or at least they did – until a woman fishing in a local reservoir caught a piranha.

The voracious, 41/2-inch, red-bellied fish with big sharp teeth is native to the Amazon. Wildlife officials suspect it was a reject from someone’s aquarium.

Hopefully, it was the only one dumped into the reservoir.

Here’s a guy who wants to take some of the fun out of life. He’s invented a dunking device to make dipping cookies in milk less messy.

David Friedman of Boca Raton, Fla., said he developed the plastic, 6-inch “Mr. Dunk” “to make dunking easier and neater for children and parents.”

Kids dunking neatly? Sorry, we don’t think the concept is a slam-dunk.

A car thief got caught because he stole the same vehicle twice.

He and a gun-wielding accomplice forced the owner out of her car late one morning. Police found it the next day.

Hours later, the thief returned and tried to filch the car again – but the owner had put a lock on the steering wheel and the perp crashed into a neighbor’s yard.

He fled, but the owner videotaped him and his bright-red outfit, which helped cops spot him and nab him that evening.

Police in Saarbruecken, Germany, mistaking a roofer for a potential jumper, sealed off local roads and called for the fire brigade and negotiators.

The roofer was so busy chatting on his cellphone with his girlfriend that he didn’t notice all the commotion below until she asked him what the sirens were all about.

Once cops realized their error, they took off – but they plan to send the roofer a hefty bill for wasting their time. What, it’s his fault?

Transit officials in New South Wales, Australia are hiring actors and frequent bus travelers to pose as irate passengers – to prepare drivers for the abuse they’ll face behind the wheel.

Those hired to vent will be paid $23.16 an hour under the taxpayer-funded project.

Perhaps if they trained the bus drivers to be courteous . . .
