Array#pop will remove the last element from the original stringified list,  
which might or might not be what you want - the methods in the other posts  
only result in a new string with the last element removed.

Also, #pop will return the popped value, not the original array, which  
prevents you from making a single-method-chain-oneliner, a popular Rubyist  
sport ;P
