Things that are wrong: Putting punctuation of the outer sentence into a quote, like

'''
I heard he said "butts?"
'''

This falsifies the quote *and* ends the sentence in a quote mark - which isn't a thing those do.

Instead, just put the punctuation outside of the quote, like:

'''
I heard she said "butts"?
'''

This has been a PSA, brought to you by me. Me - nobody else but me.
