ThatDudeCanCook - Sonny Hurrell had a long career as a line cook and head chef, and shares his no-frills, practical cooking techniques with a dash of silly humor. I'm not fond of the running gag where his dish turns out so wonderfully he beats his refrigerator to death, but his producer/sidekick Marcus is the most edible thing on the channel. You'll want to lift your muumuu and purr, "YUM."
Nemo's Dreamscapes - Long (two to twelve hour) relaxation videos that combine instrumental music or 20th century standards with ambient noise. Excellent for background noise while you're working, and I've found them to be effective sleep aids as well.
BOZE vs THE WORLD - I'm not huge on true crime, but this young lady is carving herself a nice size piece of that audience. Boze has a disarming, Wendy Williams sort of personality that makes whatever nonsense she's talking about fun. I'm a bigger fan of one of her alternate channels (Best of Bodycam w. Boze) where she reacts to police body cam videos and comically picks apart the neuroses of the perp.
Girl With The Dogs - Vanessa is a Canadian pet groomer who takes dogs and cats that other groomers can't or won't handle. She does this for free in exchange for filming the groom as content for her channel. Her dry humor makes the narration of the videos fun to watch. This is one of the rare examples of social media doing good in the world. The owners get their difficult pets a quality grooming for nothing while Vanessa assuredly makes big money with over 3 million subscribers, product and merch sales, and a series of online grooming classes. I love to see someone get rich by helping people.
SB Mowing - Similar to Vanessa above, cutie patootie Spencer finds ridiculously overgrown yards and gives them pristine cuts for free in exchange for the content. There are dozens of these channels on YouTube, but he's my favorite and IMO the most genuine. He also has a pressure washing channel in the same vein. Many people would liken watching a lawn get mowed to watching paint dry, but many others find it soothing.
The Little Rascals - The original shorts posted by Crackle.
The Luxury Travel Expert - Gorgeous hi-def videos of first class flights, luxury hotels, and beautiful exclusive resorts. Unlike the other channels with the creator constantly mugging into the camera, this man never shows himself or speaks, allowing the footage to speak for itself.
