A staff member was showing a patron around one of the library's meeting rooms, pointing out the location of the chairs, tables, the podium...
"That's not a podium. That's a lectern," the patron interrupted.
What followed was an anecdote about this patron's old grade-school teacher, who had once made a big deal about the differences between a podium and a lectern, full of snail-slow enunciations and a discourse about Greek and Latin roots. This patron had been waiting his entire life to pass on this lesson, and he was sheepishly thrilled at the chance.
This quickly became a little joke amongst staff members. Marian Librarian asks Betsy Book, "What is that piece of furniture called?" And Betsy answers, "Podium. PO-DI-UM". Marian replies, "No, it's a lectern!"

This is a podium:
And this is a lectern:
