the plunge

When getting married, it's known as "taking the plunge" because you're plunging into marriage with another person. 

One guy close to me took this idiom quite literally... 

After his wedding, him and his new wife honeymooned in Jamaica.  After approaching a 50 foot cliff over the White River, he decided to take the plunge and did a cannonball!  Well that wasn't adventurous enough, so he thought he was up for a massive belly flop from 50 feet above.  I know what you're thinking...

SMACK!  That's the sound his belly made when it slapped the water.  That wasn't the only impact that the belly flop made.  His brand new wedding band flew right in the river never to be seen again. 

Less than one week he had that ring.

Needless to say, his wife wanted to "ring" his neck.

Moral of the story:
Guys, lock your jewels in the safe when necessary (such as 50 foot belly flops). 
Don't do any extreme sports or work with them on.
Consider getting them insured. 
Do anything to avoid such an early loss!
