In one of the HIMYM episodes Barney made with Ted this conversation:


Ted Mosby:

    It's just, there are so many decisions be made. What if I make all the wrong ones and the building just sucks?

Barney Stinson:

    Not possible. Your building is new. And I have one rule: New is always better.

Ted Mosby:

    You can't keep changing your one rule if they're always different rules.

Barney Stinson:

    Ahhh... but "New is always better" is my oldest rule, which makes it the best.


Based on this HIMYF is better than HIMYM.
