Oh...now I'm really wishing Lego did more Doctor Who sets.
I predicted a doctor, along with The Doctor, but never guessed it would be several Doctors. Nice!
Also, the joke about nobody being there was really clever! I have never heard that before.

I think this one could have benefited from one more joke, and perhaps some extra breathing room between the punchlines. Since both jokes are quick, you may want to give us a bit to process the joke and enjoy it before the next one liner.
