Duffy's Real Name was Rocky

Here’s an interesting twist:  Duffy’s real name was actually Rocky.  Duffy is the bully from Day 21 who beats the pulp out of Roger after Roger acts too cavalier and over-confident around him and his hoodlum friends.  But how can you use the name ‘Rocky’ with a straight face?  You can’t.  That franchise is owned by Sylvester Stallone.  Didn't want to step on HIS toes. I didn’t want the reference about toughness to be THAT close. Also, Rocky is kind-hearted. Duffy was nasty to the core.  True, “my” Rocky came about five years before the first film about the Italian Stallion was released in 1976. But as soon as Stallone hit it big, I was keen to change the name.  That would be leading the reader too much, being too suggestive.  Duffy is another name from my childhood, so it worked out.  He was a neighborhood bully who used to terrorize us younger kids on his bicycle, riding out of the woody playground with menace and meanness.  So as soon as the Rocky movies started to come out, I was more than happy to change my character’s name to Duffy.
