Well, I didn't quite get that last one, so here are a few more of my efforts:
1) What would you get if you crossbred a Dalek with a Zygon?
A walking tin of ravioli
2) The BBC are considering developing a new sort of Dalek that squirts its victims with egg yolk. What does it say when it blasts them?
3) Which song would you play to the Sontarans to make them go away?
“Devil Woman” by Cliff Richard. As soon as they hear the bit where it says “She’s gonna get you from behind” they turn tail and run!
“You may be a doctor, but I'm The Doctor, the definate article you might say”
