I'm thinking it'd be kind of unsatisfying in some ways.
Let's say you want to tug one off, would you really be happy not doing the back one as well? Probably not... And we all know how hard it is to scratch that spot, imagine trying to grip and pull for 5 minutes!!
Personally, I don't understand why you'd get it removed.
It's like that baby in China that had a working 3rd arm, and they removed that.
Sure, it's freakish, but how many times have you wished you had an extra hand to do stuff with?
