Videos from Seth MacFarlane's Cavalcade of Cartoon Comedy! have been on YouTube for months, but they were censored versions of what would ultimately become a DVD/Blu-Ray release. That DVD/Blu-Ray launched this month (May 12th) and some of the uncensored videos were put on YouTube.
The content of the video is essentially the same, but now Mario is dropping F-bombs.
