one email of a woman who gave a dumb answer on Who wants to be a millionaire from yiling made me went on a search for that video on youtube. but instead of finding it, i found the full coverage of a man who cheated (yes, cheated!) on national tv, in the same show in 2001 in UK.
he simply read out the choices 1 by 1, and his accomplice coughs at the right answer. this is part 2 of 8. if you follow, it actually shows how he cheated his way through and won his million dollar, but of course, he wasn't awarded the money.
