A couple of slightly warped American teenagers came up with a fantastic plan to get around a family's late night internet ban -- drug the parents unconscious.

The case covers the parents of a 16-year-old girl in Rocklin, California, who thought they were being perfect mummy and daddy by enforcing a very reasonable ban on internet use after 10.00pm.

This didn't go down very well with the girl, who, along with a 15-year-old friend, obtained some sleeping pills, ground them up, put them in a couple of milk shakes and fed them to the parents. After an hour or so mummy and daddy fell asleep, leaving the kids free to blankly stare at Twitter and Facebook until the early hours of the morning.

The parents woke up at around 1.00am with "hangover like" symptoms. Having suspected the milk shakes tasted a little odd earlier in the evening, they bought an off-the-shelf drug testing kit, found they were clearly on something, then took the two kids to the police.

Quite clever, really. It's not that different from letting your wife drink a whole bottle of wine so she falls asleep early, meaning you can have a couple of peaceful hours on the Xbox. There's just a slightly higher risk of death. [Guardian]
