MFA Applications Done

What has 2 thumbs, and finally sent in the last of his 9 applications, and is pissed he had to type out his basic information seventy times, and vows for this reason that if even one of these 9 schools rejects him he will exact icy revenge (yes, on the whole school, or schools), but for now is going to reward himself by gorging on Mexican food and ice cream?

No seriously, this is a funny joke. Can you guess?
