There was a man who was born before his father, killed his mother, and married his sister. Yet there was nothing wrong with what he had done.

Why?

You’re going to a friends house and want to give them some brownies. On the way to their house you cross 5 bridges. At each bridge you must pay a toll of half of your brownies to the owner. But they are all very nice and give you back a brownie from what you give them.

How many brownies must you start with to give your friend 2 brownies?

This is a bus:

Which way is the front of the bus facing (left or right)?

Four cars come to a four way stop, all coming from a different direction. They can’t decide who got there first, so they all go forward at the same time.

They do not crash into each other, but all four cars go. How is this possible?
