20 Doctor Who Moments We'll NEVER Forget

20. Ra-Ra Rasputin (The Power Of The Doctor)

Sure, John Simm's Master wheeling an elderly David Tennant around to the Scissor Sisters is iconic, but nothing beats Sacha Dhawan's gloriously deranged disco dancing in The Power of the Doctor.

The story goes that Dhawan misread the script and effectively improvised the moment. Improvisation is key to Doctor Who's success given its persistent lack of time and money, and nowhere is this better realized than the Master busting some sick moves to Boney M while taunting the Doctor.

Possibly another perfect bit of improv was the Dalek and Cyberman actors looking quizzically at each other when presented with the Master's dance routine. It's one of Doctor Who's most chaotic and hilarious sequences from the past 60 years.
