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

Vallejo police said 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.
