In my head this was Ian Kung, but I can’t find it on his channel.

The creator was trying to make a point about how broken copyright enforcement is on YouTube by basically watching cool videos and “reacting” by saying the same thing after each one loosely tailored to the content. They were all based around the phrase “my wife” or something like that.

Like “wow, what a cute lazy dog. It’s almost as lazy as my wife,” “if you think that’s a big whale, you should meet my wife,” or something to that effect.
