Columbo episodes

Explanation why I was watching a lot of Columbo series lately:

My boyfriend is an absolutely Columbo fan (I know this sounds weird, but to be honest I like it too, since this character played by Peter Falk is just "terriffic" - like Columbo always uses to say). Anyway, Grex got the first season as a present and so we`re watching every now and then an episode in English. I hate it when the music starts and the first charachter shows up and Grex shouts out:" Oh, I know this one, it`s the one where....." But, never mind, it`s obvious anyway in every episode who is the murder, so it`s still fun to watch.
Language wise I observed that the first episodes are more challenging, since there is the original tone (later on it`s dubbed) and so the side noises are very loud. Explanation again: Grex studies sound engineering, that means I`m well informed about that kind of technique.

Well, if anybody wants to borrow a Columbo series, just tell me and if you need any further information on Peter Falk, you know who`s the expert (-:
