In the year 3000

You know what scientists need to get on?  Instant calorie counter.

I envision this like the little scanner-thing Beverly Krusher had on Star Trek: TNG that she waived over sick people and gave them shots with.  Except instead of waiving over sick/dead people, I could wave it over cake. 

And then it would tell me how many miles I would need to run in order to burn it off. 

BAM!  Just like that!  Snap of the fingers.  Easy peasy.

Does anyone know how many calories are in handmade cake from fancy bakery?  I'm going with 10 but I know that isn't right. :(
