St. Michael the Archangel,
defend us in battle.
Be our defense against the wickedness and snares of the Devil.
May God rebuke him, we humbly pray,
and do thou,
O Prince of the heavenly hosts,
by the power of God,
thrust into hell Satan,
and all the evil spirits,
who prowl about the world
seeking the ruin of souls. Amen.

I have been praying this almost everyday for the past two weeks, half trying to memorize it, and half because it is so cool. Those of you who don't know it, learn it.
