Have to chime in here and say, no offence wolfie but, after watching that part of the program, your objections to Randi seem weak. The conjuring tricks had nothing to do with the test and looked to be nothing more than simply some spontaneous light entertainment.
Randi has devoted much of his life to exposing charlatans. Including shameless con-artists like Peter Popoff. People like Randi provide a much-needed public criticism of a lot of the nonsense that can, and sometimes does, ruin people's lives.
Just so I can be sure I understand you - it seems that your objection to Randi is that he was behaving in an unprofessional way. By doing the conjuring tricks, he was being disrespectful to the person who he was about to discredit?
