Students at BYU or possibly other mormons attempt to find a loophole in the no-sex-before-marriage rule of the LDS faith.

Its quite simple.

Step 1: Drive to vegas as a heterosexual couple.

Step 2: Get a quick marriage.

Step 3: Fornicate your brains out.

Step 4: Get said marriage enolled.

Step 5: Return home and be able to say you have not had sex outside the bonds of a legally recognized marriage

And the loop hole is complete.
