Saint Michael the Archangel,
defend us in battle.
Be our protection against the wickedness and snares of the devil.
May God rebuke him, we humbly pray;
and do Thou, O Prince of the Heavenly Host -
by the Divine Power of God -
cast into hell, satan and all the evil spirits,
who roam throughout the world seeking the ruin of souls.
....while you're on your bended knees, reciting that prayer, make sure you enunciate the words, moving your tongue well, in a nice oscillating motion. The devil will release outta me soon enough.
