Rat Race

Researchers at Massachusetts General Hospital developed a technique that may grow replacement livers someday. This technique uses liver cells from rats and more or less reseeds the "sick" liver.
Can you imagine a future where instead of a liver transplant we go in for some rat cells! Will we develop a huge appetite for cheese and garbage? Will we look at these furry rodents and feel a deep bond, possibly sharing the DNA from a distant ratative? It gives a whole new meaning to the expression, "you dirty rat," which will be considered a ratist remark. Rats will demand equal protection under the law.
Oh the possibilities are endless.
