Doctor Whoops!
My username obviously gives a clue to a particular obsession of mine. The programme in question has provided a few innuendos over the years. Here’s a few, including one that was changed in the script at the last minute and so was never actually broadcast. But it would have been fun if they’d managed to slip it in.

Arf

Jamie (on seeing a space station on the TARDIS viewer screen): “Look at the size of that thing, Doctor”.
Doctor: “Yes Jamie, it is a big one”.

Doctor (having just managed to steer a space station out of planetary collision): “I think, therefore we missed”.
Sarah (realising that there’s a missile on their tail): “Yes, but we’re still heading for the biggest bang in history”.

Peri: “Where are you going, Doctor”?
Doctor: “Won’t be long. I’m just going to take a scout round the back”.

Gah
Peri was almost as annoying as Bonnie Langford's character.

But
Peri had a wonderful pair of tits.

So no problem.

Yes.

Tom Baker had a line about "taking the Cybermen from behind"
which had me chortling into my beer

I can't remember which episode, I think there was a lighthouse involved though...then again, most of Tom Baker's stuff was pure innuendo anyway

@emvee
That would have been Horror At Fang Rock, and it was the Sontarans, not the Cyberman. They were the potato-headed things featured recently.

@DG - there must be hundreds more than that along the way. I can't think of any off the top of my head, but I'm sure there were...

@b3th - it was Revenge of the Cybermen
googling "take the Cybermen from behind" brought up this - www.drwhoguide.com/who_4d.htm

Though I may be getting it confused with Fang Rock in my head.

No, no...
Horror of Fang Rock featured the Rutans, not the Sontarans...
