Make a vividly detailed and comedic fictional BBC Merlin scene script with King Arthur (played by Bradley James) deciding to relax after a long day. He takes Merlin with him and goes to the pond near his castle, tossing his clothes at Merlin until he's in the buff (compliment his butt, and physique). Describe how he looks as he enters the water to relax. Describe how he looks as he lets out a fart into the water, basking in the relief while a few fish pop up dead. He has Merlin collect them to cook for dinner.
