A teacher asks each of the kids in class what they need, as opposed to want.
Joey says "A computer."
The teacher replies, "That would be very useful."
Jimmy says "A new lawn mower" and gets a similar response.
Little Johnny pops up and says "At my house we don't need anything!"
The teacher asks him to think again carefully, as everybody needs something.
Little Johnny replies, "No I'm sure. When Obama was re-elected, I remember my dad saying, "Well, that's the last fucking thing we needed!”
