Deletion of Bozo (etymology)

Comment: the latter part of the article is simply a trivia list of various times the word "Bozo" appears in popular culture. The first part is actually an attempt at writing an etymology but it is unsourced and probably |original research. A copy of the etymological hypotheses here was added to Wiktionary's wikt:bozo|bozo entry (now removed to the entry talk page pending verification) so there is no point in a transwiki
