Variations on a Theme

I gave up swearing shortly after college, but it can be a challenge sometimes to come up with an "appropriate expression" that used to be filled with a four-letter variety.

But since practice makes perfect, and since I like language anyway, I'm gonna ask you to "fill in the blank" with a new-and-improved expression.

This week's expression is: "Holy _____!"

Holy Joseph! (the one I've retrained myself to say)

Holy Moses!

Holy frijoles!

Holy cow!

Holy rusted metal, Batman!

C'mon, give me some more ... !
