My favourite was a man who called in and said that, when he was a kid, his mother had made him a wooden dickie bow tie in his team colours to wear the match. I can't remember for sure what team it was, I think it was Partick Thistle, but it was definitely a Scottish team.
Anyway, this wooden bow tie was so heavy that it would weigh his neck down, so he would be stooping all match and have a sore neck for days afterwards. He was scared about offending his mother, but eventually told his dad that it hurt his neck and he didn't want to wear it. So that he could still take it to the match, his dad nailed the bow tie to a wooden broomstick (minus the brush). So this fella was saying, in order not to offend his parents, he went to the match all season carrying a wooden dickie bow tie on a broomstick.
Edit - thanks for the internet I just found the call. I slightly misremembered it, it was Dundee United and some of the details were wrong, but this is comedy gold with Baker and Kelly.
