I first talked about eggcorns on this blog here in this entry. I've seen a few more since then. There have been multiple occurrences of free reign for free rein in my life lately. This quote was in one of the school newsletters:

Possible eggcorn? I'm not sure if array for awry is an eggcorn or a cupertino. What do you think?
