A complete and accurate depiction of human nature in 3 minutes 10 seconds: https://www.youtube.com/watch?v=amNF_F6oeRU . :)

Four of Evelyn Lambart's shorts for the National Film Board: https://www.youtube.com/watch?v=LhGkCMgG-4A , https://www.youtube.com/watch?v=WQoeP8V5u2M , https://www.youtube.com/watch?v=ahUyhTdiZAA , https://www.youtube.com/watch?v=cUoAwd3rMZ4 . This is the sort of content that I grew up watching, on the Canadian version of PBS.

Furry animated shorts: "Die Young" animated by Vivziepop: https://www.youtube.com/watch?v=-PKNuZovuSw , "Shut Eye" animatic https://www.youtube.com/watch?v=MgNo8EoNxmo , "Hadidance" https://www.youtube.com/watch?v=3ykaGNl67iI , "Fox Fires" https://www.youtube.com/watch?v=sN5goxeTfjc , "You're The One That I Want" https://www.youtube.com/watch?v=RNK_xBAGTBI . Mostly musical, mostly amusing, should help populate your Youtube suggestions with more of the same.

Second Life furry music & dance videos (lyrics occasionally NSFW, visuals as SFW as twerking ever is): https://www.youtube.com/results?search_query=second+life+furry+dance&sp=CAM%253D . Note that the top entry in this list was made in 2011; that's practically ancient in internet time, but I'd say the whole approach still holds up.

"No Evil" series by Betsy Lee at https://www.youtube.com/playlist?list=PL_9VobYoMHhBjLjSxq5vzNW_9b00VUxiE . Starts out with a few classical and North American myths and songs, and develops into a fascinating world and story all its own.

Lucas the Spider: https://www.youtube.com/user/joshuaslice/videos?view=0&sort=da&flow=grid . It's a particularly cute spider; what more needs be said?

Sir Mashalot's top two: Six-song country mashup https://www.youtube.com/watch?v=FY8SwIvxj8o and "Even Better" https://www.youtube.com/watch?v=p0VXubTsAoE . It's hard to explain without making it sound terrible, but give 'em a try and I think you'll enjoy the music.

"Your Racist Friend" by TMBG: https://www.youtube.com/watch?v=JFGQdvYIJ0M . Thirty years old, and unfortunately more relevant than ever.

VoicePlay, https://www.youtube.com/user/theVOICEPLAYdotcom/videos?view=0&sort=p&flow=grid . I'm a sucker for a capella (or even barbershop quartets, such as https://www.youtube.com/user/BarbershopHarmony38 ), but this group is matched by only a few. Their version of "This Is Halloween", https://www.youtube.com/watch?v=YL44YFyNLys , got me to insta-subscribe before I heard anything else, and they've gone above and beyond for several others, such as "Grim Grinning Ghosts" https://www.youtube.com/watch?v=B5TYZ8GqZbU and "Zombies vs Hillbillies Survivor" https://www.youtube.com/watch?v=yYzwzbqUJXk . Even when they just do a five-minute medley of Queen, https://www.youtube.com/watch?v=krcU5xmlzqA , they can't help but turn it into something more.

Adam Savage: https://www.youtube.com/user/testedcom . Offline, I've also been binging on old episodes of Mythbusters, since I've got the time.
