Further proof that you can't keep a bad concept down: UPN has picked up the NBC-rejected reality show Chains of Love, a Dating Game update in which four people are chained to a member of the opposite sex. Each day "The Link" will unshackle one member of "The Chain Gang" until his/her ideal match is left. The show — from the team that brought Big Brother to America (thank you very much!) — will debut in the spring.
