Paging Alfred Hitchcock! A flock of turkeys has gone on the attack against--a Toyota Prius! This week on Car Talk, Tom and Ray try to figure out what's attracting the birds, and what the owner can do to discourage them? Also, three separate car owners with one goal: an encounter with a UPS truck; how to explode a muffler in one easy step; and, on Stump the Chumps, the return of Nunzio the Knucklescraper.
