Ralph Wiggum is the son of The Simpson's police chief Clancy Wiggum, a 2008 presidential candidate and, by proxy, a Scientologist.
Ralph Wiggum is a character from the cartoon series The Simpsons. He is an eight year old second grade classmate of Lisa Simpson and the son of police chief Clancy Wiggum. He is voiced by Nancy Cartwright, who also does the voice for Bart Simpson (mentioned in Cracked's The Top 10 Celebrity Scientologists).
Kind of an oddball, awkward kid, Ralph is frequently in his own world talking to imaginary friends or participating in pursuits of interest to noone but him. His interaction with others is mostly via non-sequitor observations that frequently have little or no situational relevance. He has shown to have many talents, and despite trouble communication is generally optimistic.
Series creator Matt Groening has admitted the character is his personal favorite, and he's one of the most often quoted. Chances are pretty good you already know what he is saying in each of the pictures included in this Topic Page without needing a caption.
