Has anyone heard of Angry Grandpa from YouTube?

I feel like I'm reminded about uh, y'know, stereotypes. Also, a bit off topic, but seems like those who are over 50 are more wiser, calm and knowledgeable in general in my experience. Oh, and my mom is actually born in 1964 and wow. That age gap between me and my mom sounded like a big deal. Sorry if I was off topic, but that's what reminded me. But yeah. Angry Grandpa from YouTube isn't too bad.
