Several ideas

[typecasto]

Deal with the devil: Sign a Contributor License Agreement.

Just go on without me: Have a fork of your repo overtake it in popularity.

Who were you? What did you see?!: Comment on an issue that's been closed and inactive for more than 2 years.

Bad take: Receive more than 30 👎 reactions on a single comment.

Rubber ducky: Write an issue longer than 3 paragraphs, then exit without posting it.

Conference call: Ping more than 15 people at once.

One for every occasion: Link someone a (relevant xkcd)[https://xkcd.com/979/].

i use arch btw: When asked for system information, reply with the output of neofetch.

Wool request: Submit 5 pull requests during october after submitting none the previous few months.

After all, why shouldn't I?: Star your own repo.

Dang it.

Happens to the best of us: Format a markdown link incorrectly.
