If you pour flour on someone's head it forms a cone just like a clown's hat.
If you set light to someone's hair as a party trick, it can be quite alarming, it also stinks.
You're got to turn your brain off in order to think.
You can test if someone you are phoning is still listening by asking:
Oh, could you please hold your left ear and pull it out a little way and suddenly let go.
Did it go pid-doi-oing?
And did the other ear shoot out?
