Not from Sesame Street

While driving to school, Noah announced that I was going to be quizzed on Greek gods & goddesses. After getting several right, including Dionysus (thank you very much), we had the following exchange:

Noah: Mommy, who is the Greek god of the sea and earthquakes.

Me: the god of the sea, hmmm

Noah: and earthquakes.

Me: what does it start with?

Noah: P

Me: Paul? Patrick? Pamela?

Noah: Mommy

Me: I give up.

Noah: Posey Dawn

It is Poseidon.
