that make me very happy.

In one episode, Tim and Mike hit a cyclist in their van and the writers parody a similar scene in The Sixth Sense, where Cole sees the victim of a road accident by his car window. In this episode, the cyclist is played by Olivia Williams, who also starred in The Sixth Sense (she was Bruce Willis' wife).

Peter Serafinowicz, who appears in several episodes as Tim's arch nemesis Duane Benzie, provided the voice of Darth Maul in Star Wars: Episode I - The Phantom Menace. In the series, he uses a voice very similar to that used for Darth Maul, and in one episode even paraphrases one of his lines from Star Wars. Amusingly, from the second series onward, Tim's hatred of Duane is matched only by his hatred of Star Wars: Episode I - The Phantom Menace.

He does a very good Terry Wogan impression, too!
