Odd timing, this; I've never seen a 'Columbo' episode, but I was reading a book just a few days ago about the making of 'The Princess Bride', so a character of Falk's popping up here was a pleasant surprise.
Columbo and Doctor Who!!! I never thought of that! Mind you, I did Doctor Who + Balamory on this site. I'm mad!!!
A crossover worthy of another 20,000 words.
Oh LOL!! The Master doesn't stand a CHANCE!
