How should I reply humorously when a girl says she can’t tell I’m a serious person?

The humorous reply is as follows:

1. That’s because I hid it better and you didn’t notice it.

2. I am most serious only when I face you.

3. I am too serious, you can’t tell.

4. I am just not serious in front of you, but I am still very serious in other places.
