What comes into your house every day and twice on a Sunday?

Let me guess..


It's the sun 7x + Sun+Day

So, it comes 7 days a week, plus one time on the Sunday?

So, it's Sun?


EDIT: AFFF!

Went through the replies, I was late!

Catch-22: A situation in which someone is in need of something that can only be had by not being in need of it.

Here's one:

If Pinoccio said "My nose will grow now!". What would happen???

His nose will not grow. What Pinocchio states is a prediction, which can be neither true nor false at the time it is stated.

Stop me if you heard this one before.

Three well-to-do gentlemen walk into a jewelry store at the same time, each wanting to purchase engagement rings for their better halves. The first guy ask to see in a ring in size 5 1/2. The second ask for one in a 5 3/4. The other asks for one in a 7.

The jeweler brings out one ring only, then asks all three guys will this do, of which all three were elated and said yes.

Sans the obvious adjustable-size ring, what did the jeweler show the guys?

What are the best seating arrangements for the following situations:

A man goes into an ocean-side restaurant and orders the albatross dish. He takes a single bite when the food arrives, puts down his fork, pulls out a gun, and shoots himself. Why does he do this?
