Flying to New Orleans

So I'm on an SWA from Nashville to New Orleans. On our approach the flight attendant says over the speaker "I'd bet that we've got more than a few football fans with us today (mild positive murmuring)."
"Do we have any MTSU fans?" (Silence.)
"Any UT fans?" (Silence)
"Any Vanderbilt University fans?" (Big cheers!)

She then oddly starts singing Rocky Top and gets roundly boo'd.
