Reason #3... to have a pet:

They fall sleep in funny positions.

They get so so so excited to eat, and then can't take it once they hit the point of satisfaction. Succumbing to the full stomach bliss, sleep is too hard to fight off.  Plop.

Reason #2... to have a pet:

They get super confused sometimes and make you laugh. How does this little guy's neck bend so much?! He's like an owl with that almost-180 degree rotation. I wonder if he's watching 2001 A Space Odyssey... or Keeping Up with the Kardashians. I don't understand either.

Reason #1... to express yourself:

You may find out just how high you can go. This guys gets major props for going for it. I don't know how his ears work, but it's hard to believe that he thinks he sounds as amazing as he appears to think he sounds. I kinda want to see a video of the audience's reaction. Note: if you play this at work, your co-worker may walk over to your workspace and ask if you are watching a viral cat video...

Reason #1... to have a pet:

You can put shoes on them and watch them freak out. This poor boxer cannot get the hang of his new booties, but surely he will eventually figure out that they help against the snow outside. Maybe? With those high kicks, this video should be dubbed over with karate sound effects!

Reason #1... NOT to exercise:

The Ab Hancer.

Helping unfit men feel like they could've been an extra in the movie "300" since 2008...

I would need to see before/after photos, but it seems as though, with the right lighting and blood alcohol levels, this could be somewhat effective. Temporarily, of course. Do you think the inventor was working at factory where they make black American Express cards and decided to make use of the scraps?

Reason #1... to have kids:

They try to play sports like grown-ups and look adorable doing it. I bet the little blue guy has fantastic images of himself looking like Ryu from Street Fighter - jumping 12 feet in the air, doing reverse strong kicks. And he's probably holding back so he doesn't do any real damage to red.
