Guess the last two series

[vilakins]

I have just two none left:

3. How to survive on another planet in another time. Life on Mars

10. One of them never says yes or no. SG1 (Teal'c)

Here are some more clues.

#3 is a play on both the title and the premise.

#10 is a very well-known and long-running SF series, and one character, like the Irish (Gaelic doesn't have the words) never uses them.
