I have found the internet equivalent of wit:
Not using LOL or emoticons like :) after you tell a joke.
If you use them, it's as if you don't trust your audience is smart enough to get the joke.
Laughter has two effects for the hurt soul: A medicine to sooth and heal it, or a shield to cover it.
I'm reminded of this when I thought of an episode of Friends, when Phoebe dated a psychotherapist. After he met Chandler, he said, "I don't know if I want to be around when the laughter stops and the crying begins."
A joke. I don't know if it's original to me, or if I read it on the internet and wrote it out subconsciously:
Q: What's the name of the guy who made Citizen Kane but he was also known for setting buildings on fire?
A: Arson Welles.
