What are the habitual exclamations you/people around you use?

What kind of exclamations are you use, when you are shocked/surprised/in awe?

I use 'Heavens' or 'Good Heavens'.
I saw somebody using 'Christ'.
I saw a lot of people overusing 'Oh my god'.

What about you, and people around you? What word would fill these blanks ?

___, you look beautiful today!
___, I didn't know today is the due date!
___, that's much more disgusting than I expected.

No slangy or vulgar ones please. (No cr*p, fu*k, he*l.) I want to diversify my exclamation.
