Linda Rosaire may be Pam’s twin sister, but they couldn’t be more different. Often embarrassed by her twin’s crass humor, Linda surrounds herself with a myriad of cows, monkeys, horses and geese. She’s the modern day Dr. Doolittle. She has mostly retired from the circus business and works at the local Wal-Mart. Every once in a while, her sister Pam talks her into dusting off her circus costume and performing her old dog act.
