I Know Sarcasm Doesn't Work in Writing

[Ming-Yan]

But a lot of you need to know the difference between a serious opinion and an ironic opinion. Extreme irony and sarcasm are jokes, it doesn't matter if it is false information, it is a joke.

Just keep that in mind, a lot of people aren't catching the jokes in threads.

People usually make the comment's sarcasm too obvious,
or mention that it is sarcasm (Either by a character in the *whatever the writer is writing*, or by the writer itself) later on.
