Phil and Paul were the prime goosers. Kelly, as you say, would just change the subject as soon as he could, or whenever something was brought up, start an 873-clause run-on sentence about some tech issue.
He was at his best when discussing Cunego with Harmon. Harmon gave him a question (this must have been around 2008-9, either just before or during the first parts of Lance's comeback, and possibly the 2009 Giro when Cunego said his things about not keeping up with Killer) as to why it was, exactly, that Cunego had not been able to continue to perform at the level he was performing in 2004, to which Kelly responded "it was a different era of cycling then". Harmon, either obliviously or consciously, decided he needed to press for further details, why his form had subsided, maybe he was marked more closely now, confidence issues perhaps? Kelly came back with a very firm "I said, it was a different era of cycling then". Harmon changed the subject.
