The moment we've been waiting for is almost here: season 13 of It's Always Sunny In Philadelphia is returning!
Yes, the gang comes back September 5th, and now we get the first trailer for the new season!
The question everyone's been asking is "will Dennis be back on the show for the new season?" and the trailer doesn't help much as he's KINDA there...but not really. It is said the real Dennis will appear in some capacity though!
Prepare yourself for season 13!
