... If you change the last "T" to an "M", the sentence would read: "The old man had one new ham." Now let's take out the first "E", and move all the other letters up so that each word is still three letters long: "Tho ldm anh ado nen ewh am." Now the sentence is complete nonsense. Mutations can have the ...
