Super Bad Mario is a series of videos of people hurting themselves with Mario and Luigi added to the scenes to make it look like they're the ones bringing the pain. A lot of the clips they used are classics, but Mario and Luigi definitely put a fresh spin on things. Like spicing up a boring chicken breast by marinading it in a spicy curry sauce for a couple hours before baking it! "WTF are you talking about?" I'm hungry.
Keep going for both episodes that exist so far.
Thanks to DTA, who I just made a ton of different acronyms for, none of which were appropriate enough to include.
