During the opening, as Cliff and Norm are walking out of the bar enroute to a gladiator film festival instead of accepting an offer to go fishing with Woody, Norm delivers the Latin phrase "De gustibus non est disputandum". This can be translated as "there is no disputing matters of taste".
It's the first time Norm is shown entering the bar without saying hi to everyone and everyone yelling "Norm!" This was due to the fact that Norm was deep in conversation with Cliff as they entered.
