If I said,  "this sentence is false", what would that mean?

If you believed that the sentence was false, then what it says cannot be true, right?
So the sentence cannot be false, right?
So it must be true, right?
That means it must be false, right?
...

So what's the answer?
Can you think of any more "paradoxes" like this?

Variation on yours

It's like when a Belgian guy says : "All Belgians are liars! They never tell the truth!"
