Whats your favourite Time team episode?

I am not sure which actual Time Team episode I would class as my favourite, but they have certainly produced some very good ones. The programme does tend to vary quite a bit and some episodes seem rather uninspiring while others turn out to be quite fascinating. I like the progression as they uncover different items and have to change their opinion on the actual site, sometimes quire radically.

I remember seeing that episode. They had to get in some serious heavy earth moving machinery because the viduct had been buried by later dumping of waste.
