I'm surprised we haven't had any guest appearances yet. Must be scope for some. Bruce Willis with his 'Sixth Sense' and 'Die Hard' pedigrees would be a good one, possibly Keifer Sutherland. Or maybe someone from 'Friends' (gives the opportunity for some canned audience laughter). I'm sure they could work out a way for them to appear suddenly and then bugger off again at the end of the episode. In fact, thinking about it, the whole thing could be turned on its head and end up as a variety show or a celebrity guest interview programme or maybe an adventure game programme (a la Crystal maze) - plenty of options and well, let's face it, they're going to have to do something soon....
