Did Mario Bros Air on Fox Kids? 
I know for a fact that Mario Bros did not air on Jetix, but I Can't remember worth a damn if it aired on Fox Kids. Did someone confuse it for TCC airing of the show? 

Though they've never shown it, Jetix do have the rights to Super Mario Bros Super Show, it's been released on DVD under the Jetix banner.  

Second message, true. Now, about the "I know for fact..." bit, Proof or get out.
