Desmond's S03E12 (Too Young)

Desmond can't sleep at nights so he goes to see dr. Patricia who prescribes exercise. Desmond gets a tracksuit and trainers that cost about £200 and starts behaving young. When Shirley has a go at him, he goes out and gets drunk. Michael has been ordered to go and keep and eye on him but fails. Desmond gets in a fight with a policeman and Michael tries to split them up but this leads to them both being thrown in a prison cell to cool off.
