VALLEJO, Calif. (AP) - A 21-year-old Northern California man was left hanging at a playground swing set overnight after he got stuck in the diaper-like seat for nine hours.

Vallejo police say the man made a $100 bet with his friends that he could fit into a child's swing at Blue Rock Springs Park on Friday night. With the help of liquid laundry detergent, he managed to slide his legs into the seat.

Authorities say that's when he got stuck _ and his friends took off.

A groundskeeper found the man screaming for help the next morning. Firefighters cut the chains off the swing and took him to the hospital, where a cast cutter was used to remove the seat.

The man's name has not been released.
