I tried that quite a number of times and without any success. Not only did he fail to come up with any evidence whatsoever about a number of his statements (and despite endless requests to do so) he just kept repeating them and even embellishing them further - and he thinks that putting a smiley at the end of his fabricated arguments makes any difference. However, I am merely stating the obvious as you all know what he's like (with one or two exceptions perhaps).
