David Horowitz

David Horowitz (June 30, 1937 – ) is a famous news reporter who has also made an appearance in The Super Mario Bros. Super Show!

In The Super Mario Bros. Super Show! live-action segment "The Marios Fight Back", David Horowitz appears at Mario Brothers Plumbing to interview Mario and Luigi, who claim to have created a clog clearing product that could get rid of clogs in three minutes or less.

At Mario and Luigi's apartment, after telling his viewers about Mario and Luigi Mario Brothers Clog Cleaner product, Horowitz instructed Mario and Luigi to test their product on a nearby sink. After telling Mario and Luigi to unclog a sink, he watched as Mario worked on it while Luigi gave him tools, which Mario threw away quite haphazardly.

After some work on the sink, Mario instructed Luigi to give him some Mario Brothers Clog Cleaner while he asked Horowitz if he was on nationwide television; answering Mario's question, Horowitz told him that no, he was on worldwide television. After answering Mario's question, he noticed that Mario was putting an awfully large amount of Mario Brothers Clog Cleaner in the clogged sink, but was reassured by Mario and Luigi not to worry at all, saying they were professional plumbers.

Eventually, Horowitz was accidentally knocked unconscious by Mario who, while cleaning his hands, had carelessly thrown a can of Mario Brothers Clog Cleaner behind his back, which hit Horowitz on the head.

As he lay unconscious, slumped against the clogged sink, which was shaking violently, Mario and Luigi, seeing that almost three minutes had passed and the sink was still clogged, decided to try an unclog it using some Mario Brothers Plant Food; after pouring Mario Brothers Plant Food in the sink, left their apartment for some pizza.

Eventually waking, Horowitz, regaining his bearings, noticed something in the clogged sink. Upon closer inspection, he found a horrific monster had been mutated from the clog in the sink. After almost having his arm gnawed off by the clog creature, Horowitz, in a panic, left Mario Brothers Plumbing quickly, not waiting for Mario or Luigi to return.
