joe and kelly have been dating for quite a while. they just had a romantic dinner at their favorite restaurant and watched the movie "eternal sunshine of the spotless mind." they are contemplating going out onto the ice like the actors in the movie, and lie about while watching the starry sky. they decide to try it out and slowly make their way onto the ice. as they lay there, they hear fain cracking noises and quickly get off of the lake. just as joe reaches the edge of the frozen lake and steps onto the hard soil, the ice gives way just behind him. Joe and kelly, relieved, go home hand in hand.
