GRAMMATICALLY CORRECT
Combining a question mark and an exclamation point may occasionally
be appropriate, but should be kept to a minimum.
STYLE CONVENTIONS
The question mark and exclamation point follow similar rules when
it comes to style conventions and so are reviewed together here.
• When a question mark or exclamation point occurs in the
middle of a sentence, do not follow it with a comma. This holds
whether the text preceding the mark is dialogue, unvoiced thought
with no surrounding quotation marks, or straight narrative.
Bart said, "Nonsense!" and ambled off.
"You don't really mean that?" she asked incredulously.
Did he really mean it? she wondered.
Now here was a pretty kettle of fish! I said to myself.
Who would blink first? was the question.
We had barely made it to the door when crash! everything collapsed.
• When a question mark or exclamation point appears at the end
of a sentence, do not follow it with a period, even if it applies only
to the last words. The context will make it clear to readers whether
or not the entire sentence is querying or exclamatory. For illustrations
of this, see the discussion under "Period" on page 108.
• When a question mark or exclamation point follows quoted text,
place it after the closing quotation mark if it applies to the entire
sentence, and before if it applies to just the quoted part. For illustrations
of this, see the section on style conventions under "Quotation
Marks" on page 182.
• When a question mark or exclamation point applies only to
text enclosed within parentheses, it does not affect the terminal
punctuation for the remainder of the sentence. See the section on
style conventions under "Parentheses" on page 150.
• When a question mark or exclamation point immediately follows
italicized text, italicize it as well.

Surely you didn't mean me?
Come here immediately!
