Funny.
Here's another one:
The WTC memorial, spring 2015. A father is walking along the ruins of the Twin Towers with his eight-year old son.
Son: Dad, what's that pile of rubbish over there?
Dad: Those are the ruins of the Twin Towers, son.
Son: Dad, what're "the Twin Towers".
Dad: They were two of the world's tallest skyscrapers until the arabs blew them up in 2001.
Son (after a slight pause): Dad, what're "arabs"?
