Charles Crandall "Chuckie" Finster is a fictional character from the Nickelodeon animated television series' Rugrats and All Grown Up!. He is Tommy Pickles' best friend. The character was originally voiced by Christine Cavanaugh until 2001 when Nancy Cartwright took over the role following Cavanaugh's retirement. Cartwright had previously guest-starred in the Rugrats episode "Showdown at Teeter-Totter Gulch" as the voice of the "Junk Food Kid" in 1992. He has red hair and his catchphrase is "I don't know; maybe this isn't such a good idea.". Chuckie is the third oldest out of the six main Rugrats at two. He is distinguished from the others by his irrational fear of particular objects, most notably the "guy on the oatmeal box" and clowns. He is also the only original Rugrat who is left-handed until Dil Pickles was shown to be left handed in All Grown Up, and the only one besides Angelica and Susie who has spoken an intelligible word to adults during the Rugrats series.
