Yo Mama Jokes, Doctor Who Edition

Which Doctor would be the most likely to break out the Yo Mama jokes? I suspect Sylvester McCoy, but I really would like it to be Patrick Troughton or Peter Davidson. The more dignified and or stern the deliverer, the more effective the Yo Mama joke, I’ve found. I mean, imagine George Washington comes up to you and says “Yo mama soso nasty she made right guard turn left.” How do you respond to that? You can’t, it’s George Washington. Thanks to Drew for the tip.
