that is the alphabet backwards
I can rattle it off in less than 10 seconds ( it would be faster if I could talk faster)
When I was in the 9th. grade, Mrs. Triolo was going to put the whole class in detention. She gave us one out. Whomever could learn the alphabet backwards in 5 minutes would not have to go to detention. I was the only kid in class who did not have to go.
