I'm reminded of the time Dave and me were sitting in "Gig's" (ace chippy and Greek restaurant now just 2 minutes from where I work) and they used to put a small selection of nibbles on the table for you to pick up whilst considering the menu. Dave popped something into his mouth that turned out to be a pickled red chilli- the first I knew of it was when he started gasping and went bright red! Next thing he's grabbed the jug of water on the table and knocked it back (I did say "What if that was a vase?" and his reply when he could speak was "I'd have just taken the flowers out!") He reckoned the hair in his nose combusted!
