One fine day a rooster was "mating"* he was talking as casually as he could when a smallish yellow and black (black and gold bwahaha) rat (which happens to have wings) comes along and bites his foot off and says
"Give me all of your human cheesecake." But ohoho the rooster pecks his eyes out.
"Why, you little bitch..." said the rat. The rat's eyes went fluorescent red and regeneration energy spurted from every orifice in the rat's body. The rooster back away in fear, but it was too late. The rat slowly advanced, even as he was transforming into something... quite different.
"Who... are... you?" asked the rooster.
The rat looked up and said, "I'm the Doctor and I'm here to save you." The Doctor then shot the rooster in the head but the Master caught it.
"Thought you could destroy my ship could you?"
"Are you crazy I was trying to kill the person controlling it."
"Oh, I fell really stupid right not."
"Ah, well it happens."
"Do you think it would be alright if I went with you?"
"Yeah alright I've got the tardis we can see the stars, save planets, beat the Daleks... With a lot of running!"
The End
*Foot note the term "mating" was used to say he was making someone his mate.
