Dejan noticed that if you search for [can't wow "banana"] - which is a very unusual query - it can lead you into an infinite loop if you click a specific pattern. This reminds me a bit of searching for [recursion] in Google, but in that case, it is on purpose.
He posted about this on Twitter - here is how it works. Search Google for [can't" wow "banana"]:
Then click on the "t" where it says "Must include: t."
Then it takes you to a "did you mean":
Click on the did you mean:
And then you are taken back to step 1 above.
You can also try searching for [recursion] and clicking on did you mean. :P
