Search Engine Watch Moderator, Marcia, created a thread named Google ranks #9 for Batman room decor at MSN! And she took a screen capture to prove it was on the first page. Currently it dropped to the second page of MSN results.
DaveN suggests that this is "msn trying to fix there 302 problems." Now if you look on the first page results for batman room decor you will notice the result mid way down, to Google groups;

DaveN explains that if you look at the cached result for this page shows header information of HTTP/1.1 302 Found. Hence the results above found in MSN, a 302 redirect issue.
This is speculation, but seems reasonable to me.
