Hilarious flight attendant cracks up passengers with safety speech, this week on The Feed

This week's most popular viral videos include a reporter going "overboard," a grandmother's first time on a roller coaster, a cat that really misses her owner, dogs saying a prayer before they eat, chowing down on junk food at the gym and a cabin crew comedienne.

First up, Martje shared this video of a reporter who accidentally goes for a mid-interview swim.

In the next clip, an adorable 70-year-old old grandmother named Ria feels sheer joy on her first roller coaster ride. It's part of a new series called Vodafone Firsts, which captures people experiencing new things.

Meet "Moo" the cat. She could not be happier to see her owner return home after being gone for three days, in this video from inthelife.

When it comes to getting fed, dogs turn to the man upstairs in this video.

Then, Dawson G from BigDawsTv pigs out while working out, chowing down on Twinkies, McDonald's fries, cake, ice cream, cookie dough, donuts and more.

And, a brilliant safety speech, delivered by Southwest Airlines flight attendant Martha "Marty" Cobb, has plane full of Salt Lake City-bound passengers cracking up, in this video posted by Marty SWA flight attendant.
