Sometimes people, when talking, inadvertantly make a pun (play on words) which might appear humorous in a serious situation, or flippant. If this happens, they might say "excuse [or pardon] the pun" or "no pun intended". Sometimes people say "pardon the pun" to bring attention to the fact that they have just made a pun and want the listener to know that they have punned, in case they're stupid or inattentive.
