Clutching his chest at the “huge unexpected find”, it was soon revealed to Thomas that he had been the victim of a BBC prank.
Looking excited, the auctioneer gasped: “Interesting lot this. Had a fair bit of interest this. I’ve got loads of bids here.
“Start this at £1,100. At £1,100 now,” prompting Paul, who was in on the joke, to scream: “How much?”
