Groom Cracks Up Bride at Altar [VIDEO]

You've got to hear what this Groom says to his Bride during their wedding vows. Her reaction is priceless, and their story is inspirational.

Typically wedding vows are when we all reach for our tissues, strategically placed in our purses ahead of time, for the inevitable tears when two lives are joined in holy matrimony.

This ceremony took a left turn when Andrew stumbled over his vows, and his bride can't control her laughter. The above video captures the hilarity and sweetness of the moment, and quickly went viral when it was posted to YouTube in 2009.

Andrew and Melissa Engstrom met in college, and began dating. Setting strict rules on their behavior they decided to wait till marriage before consummating their relationship.

The subsequent video, an interview conducted by strongerfamilies.org, illustrates the strength of their bond, and their choice to remain pure until marriage.
