That reminds me of last years TPC. In one of TheDamian's sessions (I think it was 'The Conway Channel') he was talking about how he wrote Inline::Files. At this point Ingy stood up at the back of the hall and shouted something to the effect of "Excuse me, who wrote Inline::Files?". TheDamian made some form of 'off-the-cuff' remark and Ingy stormed out of the session. All harmless fun (I think...) and rather amusing :-)
