BBS 75 Y Ypsilon, Why?

All over the world, we basically share the same letters of the alphabet. But, we don't all call them by the same name.  Today Wyatt and Biddy are talking about a man named Evan who visited Biddy's 1st grade classroom to talk about the alphabet in other languages. For every letter Biddy tells Wyatt about, Wyatt wants to understand the reason it's said differently. Well, as you might expect it leads to zany confusion.
