Is your past significant other more of a snake or a cockroach?

Well, you can name either after your ex this Valentine's Day!

Sometimes relationships end badly. Sometimes you want a little revenge. AND to be a little petty.

Two organizations are letting you do just that, while helping out animals.

The Hemsley Conservation Centre in the U.K. has a "name a cockroach program" going to raise money for the zoo.

Mashable reports that a zoo in Sydney Australia has launched a competition in which you can name a brown snake (one of the world's most venomous snakes) after your ex-lover.

Wild Life Sydney is asking entrants to submit an explanation why their ex deserves it along with a $1 donation to their conservation fund. They'll announce the winner on Valentine's Day, who'll also get an annual pass to the zoo.
