Either that is a funny picture of a dog throwing a birthday, or a dog getting a birthday party. Either way, funny.

Someone's 1st birthday is off to a good start...

Once again, happy birthday to our favorite internet sensation (category: cat)! Here's to another five years of boxy shenanigans!

Happy birthday, Maru! Thanks for five years of heartwarmingly hilarious videos!

Also, come back later today to see a video featuring the best Maru moments from the last year!

You know you share your life with a dog when... You have way more fun planning their birthday party than your own.
