Fixed Lego references.

Lego, not LEGOs. 5mm, not 8mm. (http://upload.wikimedia.org/wikipedia/commons/thumb/1/1a/Lego_dimensions.svg/512px-Lego_dimensions.svg.png)
Updated laundry example to be internally consistent.

Why did fold return a value, but others didn't? Why store temporary values that were discarded. "return ="?

Fixed all above.
