Idea for a game show, part whatever ...

"Time Team Extreme".  The problem with the current version of the show is that the drama is all visibly bogus.  Tony Robinson and the archaeologists only have three days to investigate the site, but this constraint is purely a figment of the filming calendar.  My proposal would be to introduce a genuine element of risk; have the planning approval granted and the mixers ready to concrete over the site to put up a housing development ... unless Tony and the Time Team can find something of genuine archeological significance there, in three days.  You could have special episodes once a series where he calls up Chris Packham with hours left to go, on the offchance of finding an endangered frog.

It ties in with my proposal a few years back with respect to Griff Rhys Jones "Save Our Historic Buildings" series, which I thought was utterly one-sided; in each case, a local property developer ought to have at least been given ten minutes to put the case that the Georgian pile in question was actually pretty dull, and to extoll the merits of the retail units he had it marked out for.
