                                                                                          nating (37)
                                                            
                          
                          
                                                           No.  While I love Nutella as much as the next person (it's so good on a sweet bread, or even just by the spoonful), I think it would be virtually impossible to swim in Nutella.  You'd either float on top, which wouldn't be so bad, or sink, which would be the death of you.
