It's Always Sunny in Philadelphia season 13 TV billboards...

Oh, the glorious terror of it all, It's Always Sunny in Philadelphia returns for another season of scheming and this time their key art has a teen horror theme, 'Sunny the 13th', indeed.

Paddy's Pub gang (Charlie Day, Rob McElhenney, Danny DeVito and Kaitlin Olson) are back for more laughs, although Glen Howerton's 'Dennis' may only return for some episodes after his departure at the end of last season (especially as he's currently the lead on NBC's AP Bio comedy which was renewed for a sophomore season).

These spoof season thirteen billboards were snapped along Pico Boulevard, La Cienega Boulevard and Venice Boulevard on August 19, 2018.

Fans of the long-running FXX comedy can also enjoy all these previous season promo billboards for It's Always Sunny in Philadelphia, which have featured homages to The Sound of Music, Children of the Corn and glam rock bands amongst others in the past.

Don't despair, it looks like the gang are safe from the crazy axeman as the comedy has already been renewed for a fourteenth season. Place your bets now on what the theme will be for next year's season artwork.
