Reason #6... to express yourself:

You can spread an important message.

Clever way to make people think about their energy use... and to make guys think about sex juuuuust a little bit more than they already do.

A canvas for many interesting photo opps...

Reason #5... to express yourself:

You can give someone a giggle while they're in the bathroom.

Bathroom humor isn't always gross... sometimes it can be very intelligent. Huufington Post has a collection of oddly intelligent bathroom scribbles that made me laugh (and I'm not even in the bathroom!)

Reason #4... to have kids:

You can dress them up all swag-like...

Nothing is better than "mini" things. Mini hamburgers, mini poodles, mini skirts... Dressing kids up like mini adults is no exception. These kids look like they could kick it on the runway, win a break dancing competition and star in an independent film about growing up short.

Magnificent.

Reason #7... to have a pet:

You can "lion king" them.

The sun comes up. The birds squawk. The new king is revealed to the world... from the dewy steps of your parents' back porch.

DAAAAAAAHHHHHHH!
Seh-VENG-yaaahhhhhh...
Va va vichee wa wahhhhh...

Reason #3... to have kids:

Their creativity will astound you.

This kid wrote an amazing letter to his local weatherman. It really shouldn't even be explained further.

Just. Read. It.

Reason #4... NOT to have a pet:

They may take you out in your sleep. Ninja cats... yeah, they're a thing. Unpredictable, undetectable, unstoppable...? Watch your back when these mystical and fiercely strong beings are hovering around. Though it will be hard to maintain vigilance when you can't even tell if/when a ninja cat is in the vicinity! Good luck, humans...

Reason #1... NOT to express yourself:

It could distract drivers.

This is so creative and hilarious, though. All I can do now is try to come up with other word plays for varying car models. There are probably quite a few options out there...
