The Royal Baby's here (it's a boy!) and it's birthed an endless number of marketer tweets. While some feel appropriate because they're from baby-related brands or companies that provide related services, others are either completely out of place, or a matter of an overzealous social media manager just trying to make sure his or her brand say something. Proof that "real time marketing" is no longer about getting credit for just showing up.

Below, we pick the best and the worst efforts. Keep in mind, they've had nine months to get this right. Have you seen any more? Tell us in the comments!

BEST

1. Pampers

Pampers put some money behind a promoted tweet to push a new video, called "Every Baby is a Little Prince or Princess," featuring soft-focus shots of babies of all shapes and sizes.

2. Oreo

It's no surprise that Oreo was one of the first ones to get to the party, with the Mondelez brand tweeting out an image of a plush velvet cushion with a baby bottle and a cookie perched on top of it. While we did expect the brand to be a little more creative, considering it had, well, nine months to prepare, it's still one of the more creative and humorous executions around, proving that when it comes to real-time marketing, the cookie still knows its stuff.

3. Johnson & Johnsons

BBDO New York created a sweet cover photo for the brand, featuring a baby in a bath, alongside the words, "Congratulations to the royal couple on their brilliant news."

4. Coca-Cola

Coke extended its "Share a Coke" campaign to the royal couple by tweeting out a picture of two bottles of the soft drink, with the labels reading "Wills" and "Kate."

5. Magnum

Here's a brand with actual British roots putting at least some effort into getting out a well-produced image that at least makes you think of the product they're trying to sell.

WORST

1. Charmin

A royal poop joke, really?

2. Delta

Delta's official Twitter account declared, "It's a boy!" and announced that the airline couldn't wait to "show you the world," along with a badly Photoshopped picture of a mobile with airplanes.

It's a boy! Welcome, Prince of Cambridge. We can't wait to show you the world. #RoyalBaby pic.twitter.com/yHuzCIMYD2

3. Chobani

Apparently people have been "stress eating" yogurt while they were waiting for the Royal Baby. This is one of the marketers that looked too hard to make a connection with what was happening.

Boy oh boy, the wait is over! We can stop the stress-eating now. An empty fridge is truly no way to celebrate. #royalbaby

4. Nintendo

The baby's not even 24 hours old, Nintendo.

5. RegusUSA

Here's the definition of wasting your money. Flexible workspace provider Regus tries to get in on the act with this inane tweet. Like Wills and Kate would ever need flexible workspace.
