It’s Always Sunny in Philadelphia has provided a twist ending to a season 1 classic, twenty years later. With seventeen seasons and more to come, It’s Always Sunny is the longest-running live-action sitcom of all time, meaning it’s crucial for the series to give a healthy dose of nostalgia now and then.

It’s Always Sunny season 17 is already nearly finished, with just two more episodes to go after “Overage Drinking: A National Concern.” The latest episode currently holds a 7.9/10 score on IMDb, placing it among the less-well-reviewed of the season. That said, there’s still an exciting follow-up to a classic episode.

It’s Always Sunny Season 17 Reveals Trey & Tammy Got Pregnant After Leaving The Bar In “Underage Drinking”

For those who didn’t recognize Trey and Tammy after twenty years, or couldn’t remember the precise story, it’s worth recapping. It’s Always Sunny season 1, episode 3 was “Underage Drinking: A National Concern,” in which Trey and Tammy were two teenagers drinking at Paddy’s Pub.

While the Gang had some difficulty deciding on the morality of Paddy’s being a home to underage drinkers, Dennis and Dee found themselves particularly engaged in Trey and Tammy’s dating life. Dee, who didn’t have the most fulfilling high school experience, took an interest in Trey, even agreeing to go with him as his prom date.

Knowing it would make Trey jealous, Tammy decided to pursue Dennis, bringing him along as her prom date. While Dennis and Dee spent the season 1 classic trying to outdo one another, they were both the real losers, as usual. We know that; we’ve always known that, and not much has changed over the years.

What we didn’t know, however, is that after leaving the bar together at the end of “Underage Drinking,” Tammy and Trey would have a child. In fact, they conceived Trey Jr. on that night, having sex in a car. As we see in “Overage Drinking,” they’ve been in an unhappy marriage for years.

It’s Always Sunny’s “Underage Drinking” Sequel Is A Wild Reminder Of How Long The Show Has Been Running

It’s easy to talk about It’s Always Sunny in Philadelphia as a long-running sitcom, but a direct connection like this really shows just how long it’s been since it first aired. To say that time is flying by wouldn’t be particularly profound, but it’s worth noting how well this series holds up as a social commentary.

While I would say that It’s Always Sunny has grown less subtle in its commentary in recent years, I think that’s par for the course with many sitcoms in this era. What’s more important is that the series is still hilarious, and the most recent episode proves that its longest-running bits are still effective.
