President Theodore Roosevelt the story goes that President Roosevelt was hunting bears when his party saw a wounded black bear cub Teddy ordered a merciful death for the cub and the story was memorialized in a political cartoon in the Washington Post seizing an opportunity a New York toy store owner started manufacturing teddy bears and the name stuck because they've just like taken to a vet that actually seems like it would a lot more humane anyway the Malayan Sunbear is also known as the honey bear because honey combs and bee larvae make up such a large part of its diet hmm bee larvae anyway you can get your very own free bear over at Tunnel Bear comm slash Linus we've got that linked below it's a VPN software so thanks for watching guys like dislike leave a comment if you have a suggestion for a future video check out our other channels and subscribe with the bell icon okay no no no lower priority okay let's get the pickups done I got a meeting
