I've been re-watching "the Invasion of Time". I forgot how funny it was to see Tom "hopscotching" down a corridor, lol.
And how I jumped when HE yelled at the Chancellor for attempting to leave the room without permission.
I also had forgotten that the Sontarans were in it. Can you say UGLY?
I was also amused when A guard asked Leela to try and not kill anyone. She was a real "scrapper". And that outfit
No wonder the Doctor kept her around, lol.
And of course I always enjoy the dialog between the Doctor and K-9.
AND, my favorite quote from the show is the Doctor saying to Leela and another woman, "I am a time lord, not a painter or decorator!" What a hoot!
I also liked where the Doctor kept walking in circles inside the TARDIS and the ladies kept badgering him about being lost. HE said that he knew the TARDIS like the back of his hand, and held his hand out, palm up. Leela, grabs his hand and turns it, back hand, up. It's the little things in life that can bring great pleasure!
Annnd, the masterpiece was at the end where the Doctor pulls out the box with K-9 MII on it and smiles.
