A rather dark example, but after the Kray brothers are tipped off as to Chandler and Miles getting a witness willing to speak against them, they waylay the real lawyer and send a fake one in his place. As soon as Miles and Chandler realize, they race for Chandler's car - which has been stolen and replaced by a real-live donkey.
And after Kent is suspended from the investigation, he goes down into the carpark for a cry...and the donkey is still there.
This conversation between Chandler and Miles:
Miles: Driving a wedge between the twins is a good idea. Bold.
