Mark Makes A Friend Peep Show : Season 1 Episode 4

Mark attends a work conference and in the process makes a new friend, Alan Johnson, which upsets the 'El Dude' partnership. This forces Jeremy to consider who could replace Mark as flatmate and best friend. Super-Hands is the potential replacement, but he doesn't match up as well. Mark grows a moustache, like his new hero, Johnson whilst Jeremy is haunted by flashbacks to 'the one bad thing' that happened when he was wrecked with Super-Hands.
