Viewers weren't exactly sure what they were watching when It's Always Sunny in Philadelphia aired its first season in 2005. Since it's debut, the show has bucked all trends when it comes to TV sitcoms - even when it comes to episode titles (the show's first episode is titled "The Gang Gets Racist"). But what started as a cult TV show with a tiny viewership has grown into one of the most loved TV series of all time that has been on air for 11 seasons and counting.
Considering that It's Always Sunny has been on for 11 years, we've watched much of the cast grow from young 20-somethings to 30- and 40-somethings. Now we're taking a look back at what our favorite characters looked like in season one vs. what they look like at this point in the show. Why? Because it's fun! It's crazy to look at some of these side-by-side pictures and remember that there is an 11 year gap between them.
Fans have watched the cast of It's Always Sunny age throughout the show - from Mac's weight gain and weight loss to The Waitress's hair color change, to the real life actors all seemingly marrying each other (Day and Ellis are married to each other, as are Olson and McElhenney).
It's time to check out how the cast of It's Always Sunny aged throughout the seasons - from first gang group date to last.
