Jeder gegen Jeden
In 2000, De Mooi applied to several game and quiz television shows as a contestant and stood out for being outspoken. (His tirade when voted off the "Weakest Link" has been featured on the show's website, video and led to a "bad losers" show which he eventually won.) He has also appeared on numerous other quiz shows including "Fifteen to One", "Countdown", "Beat the Nation" and "100%".
