Haha, awesome!

Better question would be: "Why?"

So--why did the chicken cross the Möbius Strip?

1) where is pluto ... it told me where in the sky pluto would be if i were in sheffield.

2) what is fission ... it told me about all the types of fission.

3) where are my keys? ... "Not sure, but wherever you find them, that's where they are." (sneaky!)

But I've finally caught it out!

4) "how old is my wife" !

10 year older then what she says.

It's actually easy to stump:

How many protons are in a water molecule?
It will answer how many atoms correctly (3) but it won't add up the total number of protons.

There are many others, just play around with it for 5 minutes.

Darkriku, my sister had one of those 20 questions gizmos, and that wasn't too hard to stump either. The trick was to think of something that was complex or had two categories, like "fingernail clippings" or "peacock feather"

hmm, i no
what is the exact location of this penny? (impossible to tell)

Ahem.

OOH!! OOH!! LISTEN TO ME, I have a SUPER one with no answer! And it's math related!!!

If it is zero degrees tody, and it will be twice as cold tomorrow, then how cold will it be tomorrow???

It can't still be zero degrees because it's TWICE as cold and so it can't stay the same, it has to be colder.
