i wouldn't think saying Connect playing at the end of episode 10 isn't a spoiler itself, the reason why it does i would believe would be

For two more random examples I watched recently, Asobi ni Iku yo and Wagnaria both play their openings at the end of the first episode.

<p>This questions seems answered to me, but since it isn't accepted yet, maybe I can add some more info.</p>

<p>From <a href="https://anime.stackexchange.com/questions/8194/what-was-the-first-anime-that-uses-different-ending-opening-songs-in-every-episo/18823#18823">this</a> question I have a local copy of the database powering <a href="http://www.animenewsnetwork.com/encyclopedia/" rel="nofollow">ANN's encyclopedia</a>. So with this in hand I looked for titles, that had the same songs as both OP and ED (at some point, not necessarily the same episode).</p>

<p>All title comparisons are done case insensitive to catch annotation inconsistencies. There are no checks for episodes - as long as an OP becomes and ED or vice versa at some point during the anime, it counts (once). The code can be found <a href="https://gist.github.com/JonasR/9680bd90ac681a49ef28#file-calc2-py" rel="nofollow">here</a>.</p>

<h3>Results</h3>

<p>If we only take the song's title independent of the artists performing it, there are 233 cases from 216 animes. You can see the full list of titles <a href="https://gist.github.com/JonasR/9680bd90ac681a49ef28#file-same_title-markdown" rel="nofollow">here</a>. If we only consider cases where not only the title was swapped, but it was also performed by the same artist, there are still 210 cases from 194 animes (full list <a href="https://gist.github.com/JonasR/9680bd90ac681a49ef28#file-same_title_and_artist-markdown" rel="nofollow">here</a>). In other words, there are 23 titles that not only swapped positions, but at the same time also got a new artist. Then again, upon manual inspection only 14 of these cases turned out to be true, the rest can be attributed to some kind of inconsistent annotation by ANN.</p>

<p>It is probably safe to assume there are more errors, but the numbers should at least be roughly correct. I did my best catch all of the systematic inconsistencies. (The results also confirm the three cases mentioned in senshin's answer)</p>

<p>Running along the list of unanswered questions, I came along the question about different EDs each episode. And I wondered, has there been an anime that actually switched its OP and ED during the runtime of the show? And if so, which one(s) would that be? </p>

I don't know about switching both around but in Puella Magi Madoka Magica Episode 10 rather than the ED play the OP is played at the end and Magia didn't play as the ED until episode 3

Has there been a anime that used its OP as ED and/or vice versa?

This is not uncommon - a number of shows will have a first episode with no song at the beginning, and with the OP at the end of the episode. I'll pull in some examples of this later.

There are also somewhat more unusual cases like Madoka (as Memor-X points out in the comments), in which "Connect" (usually the opening) was used as the ending song in episode 10.

From [this](https://anime.stackexchange.com/questions/8194/what-was-the-first-anime-that-uses-different-ending-opening-songs-in-every-episo/18823#18823) question I have a local copy of the database powering [ANN's encyclopedia](http://www.animenewsnetwork.com/encyclopedia/). So with this in hand I looked for titles, that had the same songs as both OP and ED (at some point, not necessarily the same episode).

All title comparisons are done case insensitive to catch annotation inconsistencies. There are no checks for episodes - as long as an OP becomes and ED or vice versa at some point during the anime, it counts (once). The code can be found [here](https://gist.github.com/JonasR/9680bd90ac681a49ef28#file-calc2-py).
