You're good friends with the turtles, you're a really big fan of cartoons, such as South Park, Helluva Boss, Moral Orel, etc... adult cartoons.
One day, you brought your computer in your backpack to the sewers, wanting to show your cartoons too your friends, unfortunately, Mikey had gone out to visit April, Raph went on patrol with Casey, and Donnie went to to look for stuff he needed for a project he's working on.
That leaves you with only Leo to watch your cartoons, he kindly accepted and sat with you on the couch with your computer on a small table...what Leo didn't knew was that the cartoons you watched weren't family friendly as he thought they were.
"So, you said this one was called...'Helluva...Boss'...right?" He asked as the first episode of the cartoon played on your computer. You skipped the warning on the start and played it.
Leo watched the cartoon calmly, expecting to see a lesson for kids in any minute.
