The Big Bang Theory

The lads amuse themselves by ribbing Penny's boyfriend, Zack, treating him as the butt of their jokes. When they later feel remorse, they enlist Zack's help to take part in a New Year's costume competition, hoping to set things right.

The Justice League Recombination is a programme presented as a single episode. It falls squarely within the episode‑type genre, offering a brief, self‑contained story that fits the series’ usual format. In this instalment, the group of friends spend some time having a laugh at the expense of Penny’s boyfriend, Zack. Their teasing is light‑hearted, but it soon becomes clear that they feel the need to set things right. To make amends, they turn to Zack for assistance, inviting him to take part in a New Year’s costume competition that they’re organising. The shift from mockery to collaboration sees the lads actively involving Zack in their plans for the festive contest. By enlisting his help, they aim to smooth over the earlier jokes and work together toward a shared goal. This change in attitude underscores the episode’s focus on repairing a brief rift through a joint, celebratory effort.
