I have to thank one of SkyDoesMinecraft's old Do Not Laugh videos for helping me solve a joke that was told to me (at the time) 4 years ago.

So it was the last day of 6th Grade. I was serving detention for having the lowest grade in my English class, and I had to stay from 10:30 till 2:30 making up my work (My detention was given to me when I had a D and I was missing 6 assignments, and by the last day, I had a C+ and had turned in all but 1 worksheet).
I was serving it with a kid who got into a fight with 3 other kids. When the teachers split them  up, the kid was still riled up and lambasted the English teacher in the jaw. They all got sent to the principal's and the one kid got a detention, and his punishment was to clean up the English teacher's room.
Shortly after 45 minutes, I finished the worksheet and started helping the kid clean the room. The teacher quickly left to go to the bathroom and the kid went "Hey, y' wanna hear a riddle?"
And I responded with "Sure".

To be continued.
