It was several years ago; and I happened to be riding on the Métro in Paris, the famed and extensive subway system found there. It's pretty safe, and used by huge numbers of people. If you don't mind the steps, it takes you to speedy subway cars.
Anyway, while riding on the Métro, there happened to be some other Americans riding. They apparently were not feeling any pain, possibly from vino or cognac, and were a little noisier than most riders. Parisians who had been working tend to be quiet.
When the car came to a stop, they yelled out "Roll Tide, Roll" in unison. And they did this at the next stop too.
By the third stop, some of the other riders were shouting "Roll Tide" too; and this built up as the car approached. It was like some seated, mobile flash mob.
After the possible Alabamians got off at the Cité exit (near Notré Dame), the remaining riders, Parisians and tourists, continued to yell "Roll Tide" at stops further down the line. They were still doing that when we exited.
I didn't know there was such Bama sentiments in Paris. Or possibly the "Roll Tide" episode appealed to the Inner Anarchist in the recesses of their Parisian hearts.
At least they didn't do the Rammerjammer cheer!
