Mr. and Mrs. Turner (The Fairly OddParents)

Mr. Turner is a major character in the Nickelodeon cartoon series "The Fairly OddParents"

Why He Stinks

 * 1) He's one of the most idiotic characters on the series (rivaled with Cosmo, who's even considered smarter than Mr. Turner)
 * 2) He's either overworked and busy or putting Timmy after himself. (Then again, Timmy wouldn't have godparents if his life went well.)
 * 3) His hate of Mr. Dinkleberg will often get the best of him, plus he's a total man-child
 * 4) He constantly leaves Timmy in Vicky's hands since he was 8, you'd think he would have figured out her true nature by now.
 * 5) He got more idiotic and destructive in the last few seasons.
