You. They were humorous because they were just silly moments. Keyword, moments. If you didn't chuckle, that fine, unlike Go which is meant to make you laugh, TT03 is mean for narrative and some splice of life moments when the Titans are on the lowdown.
To put it bluntly, take those gifs you used to shitpost and extend them as the entirety of TTGo, except add more in you face about it and spite old nostalgia fags on top for meme points.
