No.
For 30 years I’ve been trying to come up with a business idea. First with my friend Larry, then with my wife Jen. I’ve never come up with a single thing that would be worth investigating, seriously or jokingly or “crazy” or anything.
If I had, do you really think I would post it publicly on the internet? Even if it was a silly joke? How fucking stupid do you think I am?
ADDENDUM: I half expect tomorrow’s prompt to be something like post your social security number and your bank account details.
