Ok so there was a dig being carried out already before Time Team visited, and they'd made a few interesting finds. Time Team asked them to put one of them back in the ground, and cover it up, and then they would film one of the Time Team guys 'finding' it. The site crew absolutely refused to fake something and for a TV presenter to take the credit for the find of one of their people (who may well have been a volunteer, I don't remember, but difs tend to rely on volunteers for a lot of work), and they were all pretty disillusioned with the show after that. Also, apparently Tony Robinson was a twat, really rude and shitty to everyone, which is a real shame, because I loved him in Maid Marion and Blackadder when I was younger.
