Oh such political correctness... It was the line that I found funny, not the implied threat of violence (which is poor considering tidal waves probably killed millions and the characters got within a fraction of a second of nuking a huge monster in the moon, and several characters were killed onscreen by giant germs).
Would it be funny if it was male to male? Yes.
Would it be funny if it was male to female? I would like to hope that a female doctor would have handled the situation ENTIRELY differently. I rather suspect the previous dozen Doctors would be spinning in their graves, if they had them, at how this went down.
