This is the video I saw: https://www.instagram.com/reel/C0gPnVluYL7/ (I swear my comment isn't an ad lol). I thought that was just the way he talks, but then I watched his other videos and he does so many other accents. They actually seem like decent quality products.
I don't mind ads that are unique in some way, and not produced by a marketing agency that seems to use the same approach for all their clients (like car ads).
