Bob Barker — come on down! The retired host of “The Price is Right” has made a $230-thousand contribution to Chimp Haven in Keithville. The money is to begin building bedrooms and a habitat for five chimpanzees that need a permanent home. They were left behind at a facility in Texas that went bankrupt. Barker’s also underwriting the cost of their care for a year. Chimp Haven President Linda Brent says she hopes that Barker’s generous donation will inspire others to contribute as well.
