In Cookie Clicker, there is an upgrade called "One Mind". Besides giving the usual bonus to something (in this case grandmas), it comes with a red warning: "Note: The grandmothers are growing restless. Do not encourage them."
If you try to purchase it the page pops up a warning:
Warning : purchasing this will have unexpected, and potentially undesirable results! It's all downhill from here. You have been warned! Purchase anyway?
With the options to purchase anyway or cancel. So far, I've always canceled.
What happens if I buy "One Mind"?
