What would be the ideal parenting test?

This is tongue-in-cheek, people, so don’t freak out on me (though it’s not the worst idea to test people before they can have children even if the idea would be ludicrously difficult to implement). Post a task that you think would be a good predictor of whether someone will be able to handle parenting. Here’s mine:

If you are able to successfully dress and bundle up 2 or more children under the age of 5 given that:

a. One of them suddenly has to poop.
b. You have a specific bus to catch to the ski resort.
c. Tickets must be printed out from your email and you forgot.

without losing it and hitting either yourself or any of your spawn and ending up on the bus in time, you are ready to be a parent.
