A couple of stories that stand out in my mind were the time he claimed to have found a tin of beans behind a shelf from “the early 1980s”, the juice inside having turned to acid (because it was so old) – but because it was acid, he’d had to throw it away before he could show anyone. This was in spite of the fact that it was 2001 and the store had only been open for a couple of years at the time.
The other classic was the time he told us about his exciting weekend rock climbing. Nothing too sensational about that, wholly believable and reasonable except for when he went on to explain that the spot in the middle of his forehead (that had been there for weeks) was in fact a wound where a deadly snake had pounced at him when he was abseiling across a cave mouth. “It was poisonous so I should have gone to the hospital but I’ve been bitten so often that I’m immune” he lied.”
