User:Epsilon the Eternal/Sandbox Four

The second episode of the first series of produced by the BBC,  sometimes mistakenly identified as the third, was broadcast on 13 September 1986. The episode was notable for being a crossover with Doctor Who; it starred Colin Baker as the Sixth Doctor presenting continuity announcements for the in-universe series, as the series was shown to be a show-within-a-show.

Plot
The Sixth Doctor disdainfully introduces an episode of BBC3's Roland Rat: The Series, and then proceeds to inanely cry out "Yeeeaaah!" — Roland Rat's catchphrase.

After the episode finishes, the Doctor is awoken by the prodding of a pole. He recaps the audience on what they had been watching, and then excitedly tells them to switch over to BBC1 to watch Doctor Who, which he refers to as "the series". Ron Rat jumps up, calling Doctor Who "rubbish" — an act for which the Doctor attempts to murder Ron, using a ray-gun he just happens to have on his person. Fortunately for Ron, the Doctor is a lousy shot.
