Super Mario Bloopers OMG is a flash screamer. It shows tons of hilarious Super Mario Bros-themed animations, such as Mario using an excessive use of fireballs, which kill Bowser and Cub from Happy Tree Friends, and Mario fighting with Flippy (also from Happy Tree Friends, this blooper is unseen). But at the end of the last blooper, a edited image of Luigi screaming (From the Luigi's Mansion Cover) with bad rotten teeth pops up with the same scream from What's Wrong With This Picture, then shows a flurry of dead bodies, but then shows a man in a black suit holding a gun. He appears alive, but then the gun turns into a stick of dynamite which explodes, and the Flash ends for real. The very last animation might take fear out of the viewer.
