self-aggrandization defined

I like the Super Bowl as much as anyone, but isn’t it funny that it’s like the only event that uses Roman numerals to state which in the series it is? How would this work in other areas of life?

“My wife turns XXVI this year.”
“Happy III’d anniversary, honey!”
“Wow, is it really the LXXI’th National Peanut Festival this year?”

Actually, it does provide a little fun watching people who normally have nothing to do with Roman numerals do mental gyrations to figure out exactly which number it is this year.
