My goodness, he was lucky, wasn't he.

[Uncanny]

This is from a test paper:

My goodness, he was lucky, wasn't he.

I guess the punctuation is wrong, isn't it?

 

[emsr2d2]

My goodness! He was lucky, wasn't he?

That's how it should look.

My goodness! He was lucky, wasn't he?

Or:

My goodness, he was lucky! Wasn't he?

 

[tedmc]

My goodness! He was lucky, wasn't he?

Or:

My goodness, he was lucky! Wasn't he?

The first, in the form of as a question tag, looks more natural to me.
