These Unusual Marriage Proposals Put a New Twist on Tying the Knot

"Will you marry me?" is a simple question, but it turns out there are lots of ways to ask it. Some couples have gotten engaged in some very interesting way, including one man who used a Hawaiian vacation yoga session to ask for his girlfriend's hand. She was upside-down at the time. A volunteer firefighter used a fake training session to pop the question. And another would-be groom pretended the helicopter in which he and his girlfriend were traveling was going to crash, before giving her a ring.
