(The show’s rare forays into disappointing flashback episodes being the exceptions.)

The Gang is never more dangerous than when they have a reason to get heated.

(Not even Mac’s quick-thinking move to eat the order could save the day.)

“The D.E.N.N.I.S.

Sadly for him, once the horrified Dee challenged him to “re-D.E.N.N.I.S.”

IT’S ALWAYS SUNNY IN PHILADELPHIA “The Gang Gets Held Hostage” (Season 3, episode 4)

FXX

(Dee got it instead, naturally.)

That, and hunting down and murdering the swarms of rats that infest Paddy’s.

One ofSunny’s most impressive and enduring feats is how it can play with our empathy.

Plus, the show’s past and future history with flashback episodes has been almost uniformly disastrous.

And while it’s a dirtbag denouement, it’s about as close asSunnygets to “Merry Christmas.”

But when it came, it wasn’tAlexandra Daddario’s lovely Ruby holding the knife but Charlie.

(“She’ll bounce back, she’s constantly being crushed,” Dennis said of his sister.

“Or she won’t.

It doesn’t matter.")

She doesn’t say yes right away.

She says no to a man, for years.

For, like, 10 years.”

IT’S ALWAYS SUNNY IN PHILADELPHIA “The D.E.N.N.I.S. System” (Season 5, episode 11)

But this episode showed the true peril of Charlie loving someone back.

With able deadpan support fromReno 911!

(“Her mouth was still very much in play,” Frank assured, through tears.)

(“It’s very generous,” he said of the graphic doodle.)

Fight back at us!”

AndSunny’s wheel of pain spins on.

(It’s been nominated three times for stunt coordination.)

(“What is a pun?,” Mac finally growled in alpha-male confusion.)

Or plotting to use the never-before-mentioned “yuck puddle” to drive all the inconvenient paying customers away.

The music swelled, all was forgiven, and Dennis Reynolds had a grenade launcher.

Happy Valentine’s Day from Paddy’s Pub.

Dee, imagining herself exempt, entered with popcorn and a gloating “Time’s up!”

Sunnyoften sees the Gang splintering into factions whenever a touchy subject rears its head.

Even the rest of the Gang had to admit it Dennis can out-evil the worst of them.
