Howling:Breaking the Fourth Wall

In the show's history the fourth wall has been broken a few times in clever ways.

The Dalek's Master Plan - The First Doctor wishes the audience a happy christmas. Rememberance of the Daleks - Ace hears someone talking about a new sci-fi program on the TV in England, 1963. Blink - The Angels never move even if the audience are the only people who can see them. The Wedding of River Song - DOCTOR WHO? DOCTOR WHO? DOCTOR WHO?

I'm just wondering are there other episodes of DW, TSJA or TW notable for breaking the fourth wall? 87.102.117.106talk to me 18:36, January 6, 2012 (UTC)
