A pet store owner has a parrot with a sign on its cage that says "Parrot repeats everything it hears". Andrew buys the parrot and for two weeks he speaks to it but it doesn't say a word. He returns the parrot but the shopkeeper says he never lied about the parrot. How can this be?

A Problem With My Lamp

You are standing in front of a room with one light bulb inside of it. You cannot see if it is on or off. Outside the room there are 3 switches in the off positions. You may turn the switches any way you want to. You stop turning the switches, enter the room and know which switch controls the light bulb. How?

Okay, I do actually have a real problem with the lamp in my living room: I don't have one. It's very dark in here.
