This is the result of what happens when characters are voiced by only a handful of voice actors. Often you might hear characters that sound the same. Related to Only Six Faces. The Simpsons is probably one of the most famous shows to be voiced by a handful of voice actors for a majority of the main characters, though they're so good at changing their voices that the trope is subverted and all of the characters sound pretty distinct. Most of the adult male characters voiced by Dan Castellaneta, Harry Shearer, and Hank Azaria. Played straight with South Park, as Matt Stone and Trey Parker voice most of the characters. Gets funny when a one shot character sounds just like Mr. Garrison. Homestar Runner also plays with this trope, as The Brothers Chaps voice most of the characters (though somewhat Justified due to there only being a handful of main characters).
