    "Now, a clever man would put the poison into his own goblet, because he would know that only a great fool would reach for what he was given. I'm not a great fool, so I can clearly not choose the wine in front of you. But you must have known I was not a great fool; you would have counted on it, so I can clearly not choose the wine in front of me."

    split the pills into three groups.

    2 pills, 3 pills and 3 pills

    weight the 3 pills to the 3 pills

    if they weight the same then the 2 pills have one of the poison pills. weight them and one is heaver.

    if the 3 pills against the 3 pills do not weight the same then the 3 pills that is heavier has the poison pill

    pick 2 of these pills and weight them

    if they weight the same then the extra pill is the poison pill

    if they do not you know what pill is the poison pill

    Just don't swallow any of them. You won't have to weigh them at all!
