New TV show Filthy Cities begins this evening, with a feculent romp around medieval London. We've been looking forward to this one ever since we accidentally followed presenter Dan Snow down into the Fleet Sewer last year.
The show combines CGI graphics and Dan Snow's gameness for wallowing through shit to recreate the noisome conditions of 14th Century London.
He spends the night as a medieval muck-raker shifting a staggering six tonnes of excrement, and has a go at medieval butchery to find out what the authorities were up against.
The Telegraph has put together a list of ten disgusting facts about the medieval city...in no particular ordure.
Filthy Cities: Medieval London is on BBC2 at 9pm tonight (5 April).
