Huh?

While running an errand today I spotted a license plate cover that said-

"Give Blood- Get Married"

Whaaaaaaaaat?

If they're trying to send a message, I don't get it. Are they making fun of marriage? Are they all for it? Are they just trying to squish two things they are passionate about on one license plate cover? Are they equating marriage with giving blood? Why? How?! Maybe they're saying marriage sucks the life out of a person, which I whole-heartedly disagree with. Or maybe they're saying that people should give blood and get married; two good things in life, two ways to give of yourself to other people.

Anyone have any clarification to offer me?
