Michigan and Florida State played in last season's Orange Bowl, but other than that the programs share practically zero history. The 33-32 'Noles win was the pair's first meeting in 25 years. Jim Harbaugh and Jimbo Fisher have traveled in separate circles in their respective climbs up the coaching ladder, too; Harbaugh on the West Coast and in the Midwest, Fisher in the South.
Yet that hasn't stopped the two sides from yapping their gums at each other on Twitter this week.
It started when FSU recruiting coordinator Tim Brewster tweeted this on Saturday.
Harbaugh seemingly let the tweet pass then, in Donald Trump fashion, remembered staying true to himself requires letting no insult go unreturned.
Brewster kept it going with a shot of Florida State's Orange Bowl ring.
I'm not sure why this spat was started, I'm not sure why it was fought and I'm not sure who won. But I'm glad it happened. I think.
