Reggie Rat
From Tardis Wiki, the free Doctor Who reference
After the Sixth Doctor finished telling the audience that they had been watching Roland Rat: The Series, and that they should now switch over to BBC1's Doctor Who, Reggie Rat jumped up, shouting that Doctor Who was "rubbish". This caused the Sixth Doctor to promptly attempt to murder the rat with a ray-gun he just happened to have on his person.
Fortunately for Reggie, the Doctor was a lousy shot. (TV: Untitled [+]Loading...["Untitled (1986 TV story)"])
