Corpora: corpus evidence that runs counter to intuition?

[Sebastian Hoffmann]

Dear corpus list subscribers

I'm looking for "nice" examples where corpus evidence (radically)
runs counter to intuition (of a native speaker) or to standard
perception of the language. Of course there are many findings in
corpus-based studies that could not have been established by
introspection - but I'm looking for the kind which would result in a
"wow - I wouldn't have thought that!"-reaction from the average
language user. ;-)
Many thanks in advance!
