Thread: Most influential catchphrases you can think of?

There are some that are so ingrained into our minds that you only need to say half of it before most people know the rest.

For example:
''The Futures Bright....''
Or
''Have A Break....''

Some are just iconic in the sense that the mere mention of phrase instantaneously brings up images f it's logo.

For example:
''Just Do It''.

Can you guys think of any others?
