S1·E20 The Bodyguard Strikes Back

Mike has his life threatened by a bus driver he has upset. The paper hires a bodyguard to protect him, Brian!

Mike does not like the idea of Brian following him around everywhere, at least not until the driver turns up in his bar with dynamite strapped around his body. Brian leaps to action, pushing Mike to the ground and diving on top of him.

Now, much to Kate's annoyance, Mike takes to Brian and they become good friends.
