Ruling on an incorrectly mucked hand?

I wasn't paying attention because I was waiting for his obvious call once the BB folded.

I was definitely not angle-shooting here.

After you've been pushed the pot, when should you release your hand... do you declare to the table... does anyone have any cards left.

Since it was so small, just chop, but the question still remains...
