I've fallen down some weird internet holes before, but somehow I went from "this fanart below" to "there's a company in Bangladesh, called New Zealand Dairy, that makes OC do-not-steal versions of Doritos and Oreos" in...like, six or seven clicks.
It might be that, but also I think they didn't like each other anyway and Missouri leaving for the SEC only accelerated that.
See also, Texas-Texas A&M probably only playing each other again because they'll both be in the SEC and have to.

Huh, so apparently Missouri wanted nothing to do with possibly playing Kansas in a bowl.
