I have read and seen many Spanish exclamatory and interrogative sentences on the internet.
But all of them were exclusively exclamatory, or exclusively interrogative.
I have never seen a sentence to be both interrogative and exclamatory.
For example, we have:
¿De verdad estás bromeando?
¡Oh Dios mío!
Now, do we have this kind of sentence too? :
¡¿De verdad estás bromeando?!
