  Python

  from sys import argv  # This import allows this script to operate as a stand alone executable
  from random import shuffle # Required import
  
  # For "single word" string
  def innerShuffle(inStr):
      temp = list(inStr[1:len(inStr)-1])
      shuffle(temp)
      return inStr[0] + ''.join(temp) + inStr[-1]
  
  # For "sentence" string
  def innerShuffleSentence(inSent):
      output = ''
      for word in inSent.split():
          innerShuffle(word)
          if output is not '':
              output += ' '
          output += innerShuffle(word)
      return output
  
  # Example Usage
  # "Main"
  if(len(argv) > 1):
      for arg in argv[1:]:
          print innerShuffle(arg)
  else:
      print "No args given. Observe strambling 'omlettes': %s" % innerShuffle('omlettes')
      print innerShuffleSentence("Now observe your ability to read a whole sentence that has been scrambled by the derived function") + ' innerShuffleSentence()'

  pretty simple in haskell:

  import System.Random
  import Data.List
  
  main = do
    g <- getStdGen
    putStrLn "Word to scramble:"
    w <- getLine
    let r = next g
    let x = scramble w $ mod (fst r) ((length w) - 2)
    print x
  
  
  scramble :: String -> Int -> String
  scramble old@(x:xs) i = if new == old then scramble old (mod (i+1) (length old - 2)) else new
      where
          scramble' ys = permutations ys !! i
          new = (x : (scramble' (init xs))) ++ [last xs]

  javascript doesn't have a built-in shuffle, but I did steal David's sentence :-)

  function innerShuffle(sentence){
  
      var sentenceArr = sentence.split(' ');
  
      for(var i = 0, len = sentenceArr.length; i < len; i++){
          sentenceArr[i] = shuffle(sentenceArr[i]);
      }
  
      return sentenceArr.join(' ');
  
  
      function shuffle(str){
          var len = str.length;
  
          if(len < 4) return str;
  
          var midStr = str.substring(1, len - 1);
          var randArr = [];
          var retVal = '';
          var i = 0;
  
          for(i = 0, len -= 2; i < len; i++){
              randArr[i] = [midStr.charAt(i), Math.random()]; //[each letter in sequence, random number] 
          }
  
          randArr.sort(function(a,b){ 
              return (a[1] < b[1] ? -1 : (a[1] > b[1] ? 1 : 0));
              }); //sort the multidimensional array by the second element within each element
  
          for(i = 0; i < len; i++){
              retVal += randArr[i][0];
          }
  
          return str.charAt(0) + retVal + str.charAt(len + 1);
      }
  }
  
  console.log(innerShuffle('Now observe your ability to read a whole sentence that has been scrambled by the derived function'));

  Clojure:

  (defn inner-shuffle
    [value]
    (str (first value)
         (->> value (drop-last) (rest) (shuffle) (reduce str))
         (last value)))

  Solution in C++. Sadly only works with words.

  #include <iostream>
  #include <string>
  #include <time.h>
  using namespace std;
  
  int main(){
      srand(time(NULL));
      string word;
      char wordSwap=0;
      cin >> word;
  
      for(int i = 0; i < word.size(); i++)
      {
          int random1 = rand() % (word.size()-2)+1;
          int random2 = rand() % (word.size()-2)+1;
  
          wordSwap = word[random1];
          word[random1] = word[random2];
          word[random2] = wordSwap;
      }
  
      cout << word;
  
      getchar();
      getchar();
      return 0;
  }
