Mnemonic

Heard on NPR, a mnemonic for the names of the planets:

My very educated mother just served us nine pizzas.

I somehow made it way past twelfth grade without hearing this charming sentence.

Thinking ahead: If Pluto loses planet status, nine can turn into nachos, and the kids won't go hungry.

Update: More than pizza is at stake: new planets may be on the way, as an AP article describes. The possible lineup: Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon, "and the provisionally named 2003 UB313." Which might yield

My very educated mother Ceres just served us nine plump chicken tacos.
