Rule 65 of the Internet:
Any use of the word "irony" on the internet is incorrect.
Person 1, posting on an internet forum: "Dude, you totally don't understand irony. Irony isn't just a simple coincidence, it's more than that. Way to go, Alanis."
Person 2: "I'm going to go ahead and invoke Rule 65 here."
When no other rule can be applied to a situation, Rule 65 applies.
