Prospects

Season 1, Episode 5: Rodent avengers

Select Source

Pincey and Billy become pest control experts, and take the work of another rat-catcher who does his best to get his own back. At first things go really well, but then the binmen accidently pick up their bottles of whiskey promised to a dour Scots customer, and they realise they should've set traps for the rodents, as usual things start to go pear-shaped.
