My friend's ex-girlfriend is a born-again Christian.
One time him and some friends were sitting in her living room waiting for her to get ready so they could go out, and she runs manically down the stairs yelling "PRAISE GOD MY SAVIOR", opens the front door and dives headfirst into a snowbank.
I made up the snowbank part, but she did run outside and fall down crying.
My friend said she was the best sex he ever had.
Then she cheated on him.
