Videos of a cat who sings duets with his owner, a little boy who stuffs an amazing amount of spaghetti up his nose, a piñata party gone amok and a mouthy little old lady minister who has the last word at a noisy wedding are among the finalists for the $100,000 grand prize. For the first time ever, votes for the grand prize will also be taken from viewers who logged on to abc.com, as well as members of the ""America's Funniest Home Videos"" studio audience.
