Once I saw this guy on the Internet about to post. I said, "Do you believe in Federation?"

He said, "Yes."

I said, "Are you using BlueSky or ActivityPub?"

He said, "ActivityPub."

I said, "Me, too! Mastodon or PixelFed?

He said, "Mastodon."

I said, "Me, too! What TLD?"

He said, ".social."

I said, "Me, too! Big instance or small?"

He said, "Big."

I said, "Me, too! Which one?"

He said "Mastodon.Social."

I said, "Die, heretic!" And I defederated him."
