Cledus, Weird Al are, for me, cut from the same cloth as Roger Miller (and probably many other similar ones before) More than a trick, it seems like another mode of 'genius'.
Deana's beating up Cledus for mispronouncing her name. In my defense, it's almost completely senseless when the spelling and pronounciation of your name don't match. Cledus: Damn right! If yer name's pronounced "dee-na", then why in the hell's it's spelled "dee-anna"?
