Vote for Bob!: You have to keep your head on a swivel when you find yourself in a vicious... uh... doll fight. And putting a head on a swivel is just what the Portland Beavers are looking to do with their next promotion: making a bobblehead doll in the image of Bob L. Head. After a spring search nationwide for people named Bob L. Head, the Beavers have given the nod to three candidates. Shaking off the rest of the field appears to be, well, Bob L. Head from Maquoketa, Iowa, who is not only getting the most thorough campaign coverage, but he also has a daughter named Bob L. Head. Weird.Remember, your vote counts, but I'm telling you right now there is just no way the winner won't get a big head.
