Expressing Surprise and Disbelief

Expressing surprise:

That’s a surprise.

Wow! What a surprise!

This is such a nice surprise.

I must say it surprises me.

I’m completely surprised.

That’s very surprising!

I find that very surprising.

How very surprising.

I find it extraordinary.

That’s incredible!

It’s unbelievable.

Wow, man! That’s awesome.

Really?

Oh my gosh / Oh my God.

My goodness.

I had no idea.

I never expected it.

I didn't have a clue about this.

Expressing disbelief: You’re kidding! / No kidding! / Are you kidding? You’re joking! / You must be joking! You’re not serious. / Are you serious? I don’t believe it. I don’t believe a word of it. I can’t believe it. That’s hard to believe. I find it hard to believe. I can’t believe my ears. I can’t believe my eyes. You don’t believe it. Do you?

Seeing is believing. It can’t be true. Oh no! That’s not true. I don’t trust you. That’s impossible. Oh, really? Is that so? I don’t think so. I can’t think of it. You don’t say. Oh, come on! Don’t make me laugh.
