This week’s viral videos involve the usual suspects: cats and dogs at their best, gravity fails and a live performance of “The Circle of Life.”

For one cat, vanity is just a part of everyday life. Rigby the cat can’t help but admire his reflection and probably ask himself existentialist questions about life. Then there’s Snoopy, the super dog who hasn’t earned his flying license yet –– and shows it by failing to fly onto a couch for a smooth landing.

If you’ve ever wanted to know more about the “floppy-floppy spider of the sea,” otherwise known as an octopus, look no further than this six-minute video that gives you the low-down on these creatures.

While gravity comes naturally to most of us, it doesn't always work out for everyone or anything — like a FedEx delivery truck. See how one man loses his fight against gravity pretty poorly.

Meanwhile, one group of airplane passengers finally got to know what it really means to have a great in-flight entertainment. The cast of “The Lion King” in Australia sang “The Circle of Life,” as passengers and crew boarded the plane. It’s a heartwarming video not to be missed.
