I must be too old because I didn't get it.

It's from the movie Billy Madison. There was a family of bullies with the last name of O'Doyle, and everytime they picked on someone afterwards they would say "O'Doyle Rules". They eventually had an incident with a banana peel, but you'll have to watch the movie for that one ;)

You're not alone :) Now off I go to check if Billy Madison is on Netflix.

prob the biggest reason i don't like these type of comments is that the replies will really never be interesting. there is no way for them to be, by nature of the parent not being interesting

and i'm not even shaming you, but finally creating words for my thought when i'm irritated heh

edit: by nature of the parent comment, you are able to unfold the origin of the name (and there was no reference elsewhere). ok, fine then :P

You are not I assure you.

He does have drawing of O'Doyle at the top of the readme.

not at all. I'm a 90s child and found this hilarious
