because the cake is a lie.

If the cake is allowed to be present and eaten at the same time, the tidal and centrifugal forces pulling through its fabric simultaneously will unravel the space-time continuum quicker than you can say "omg the tidal and centrifugal forces are unraveling the space-time continuum." Luckily we don't have to worry about this at all since we all know that the cake is most definitely a lie.

How can you have any pudding if you don't eat your suppper?

Perhaps the concept itself is flawed/illogical. Can one still have the proverbial cake even after the point of consumption. It may also be possible that the cake idiom is limited in application and, in a more extreme view, pedantic. The "can't have your cake and eat it to" example requires a specific definition of "have". What does the saying mean, precisely? Consider the fact that idioms can and do contradict each other.

Beans Ringo, beans.

I brought cake last time. It was funny how many people were skeptical of it's authenticity.

Actually Knob, I believe the word your searching for is meat.

Actually it's meat not supper or beans.

Here I am... 9AM on a Thursday morning, adding yet another crappy day to the list of crappy days this week (Trust me, even this early it's been bad enough to count the day as crappy), and what do I find?

These posts. I couldn't help but laugh. You guys rock.

In Russia, the lie is a cake.

Prior to eating said cake, you have it. It's yours. You still have it while you're eating it. At that moment; alas. You have your cake /and/ you're eating it too.

Unfortunately, cake is, well... delicious. This means that as long as you're eating a finite amount, it will inevitably run out, and you'll be without cake.

Though technically, it's still with you -- if only for a little while.

Learn to bake cake, then you can do both. I ate my cake last evening and had a second already made. And no, I'm not a mage.

Hmmm, better go make another one now, as the one that is already made is calling my name.

STAND STILL, LADDIE!

Once you take said cake out of the box, it can not exist in both states of 'had' and 'eaten'. This is known as the Schrodinger's Cake theory.
