Deja Vu - Yet Again

The three Susans were singing "I'm going to spend my christmas with a Dalek", when the six K9's announced their intention to become trapeze artists. Everyone looked at them and laughed.
A heated discussion began taking place. "Alright, then - spoons at ten paces!" cried the 7th Doctor to his NA counterpart.
A black armoured figure smashed through the door.
"So," it said, pointing at the Other. "You have returned, Obi-Wan."
"Quick! Fire the canon!" shouted Avon.
"I suddenly have this feeling of Deja Vu" said Doctor Who. Roz looked at him.
"Booga, booga, booga, booga booga." she said.
