An 'It's Always Sunny' star made an interesting cameo in new 'Game of Thrones' episode

Okay, everybody, no excuses for spoilers now; it's been a whole two days since the premiere of the eighth season of Game of Thrones, and there's a fair bit to unpack.

We've got rising tensions as Jon Snow looks like he might be forced to choose between his family and his new love Daenerys (who's just getting on swimmingly with his family), there's the long-awaited reunion between Jaime Lannister and Brann Stark, plus that one terrifying bit involving a child pinned to a wall.

There's a really cool new opening credits sequence to gush over:

There's also, of course, the memes.

But as the dust settles on the curtain-raiser for Game of Thrones' curtain-closer, there's a tiny cameo during the episode that you probably missed. Even better, it features a certain actor from the popular sitcom series It's Always Sunny In Philadelphia.

If you're a fan of It's Always Sunny, you'll be quite glad to know that Rob McElhenney, one of the creators of the show who plays the character Mac, made a very quick appearance in Sunday night's episode of Game of Thrones. It's pretty unlikely, though, that you'll see him in future episodes.

Once you figure out where he shows up, you'll understand why.

In between the Stark family drama and Cersei Lannister's obvious disappointment that we won't have any elephants in Westeros any time soon, there's a plot line that's kind of flown under the radar.

Of course, Theon Greyjoy's had it worse than anybody currently still alive on the show, but Game of Thrones is set on giving him his own protracted redemption arc. The latest chapter of that particular story took place on Sunday's episode.

He storms Euron Greyjoy's ship as he tries to seduce Cersei Lannister, to free Yara from capture. But as he does so, two random henchmen get shot in the eye, in typically brutal Game of Thrones style. But guess who one of those henchmen was?

Yup, that's Rob Elhenney getting shot in the eye, and my only regret is that he didn't get to test out any of his sweet karate moves before he met his opthalmological demise. The actor himself confirmed he was in the episode in a typically funny Instagram post, which he just captioned: "don't blink."

His co-stars on It's Always Sunny were pretty happy for him. Fellow show creator Glenn Howerton (who plays Dennis) replied "You got got, homeboy", in relation to his grisly death, Mary Elizabeth Ellis-Day - who plays The Waitress - complimented him by saying "God, you’re good at acting".

Even the official It's Always Sunny Instagram account chimed in, saying: "Gonna be hard to perform ocular pat downs now." I didn't think the two shows could combine, but now I've seen it, I want nothing more.

I keep looking at this episode two preview and trying to spot Danny DeVito or Charlie Day:

Well, there you have it, folks. Ed Sheeran, Mac from It's Always Sunny - who knows who'll show up next in Game of Thrones? Donald Trump? Shaquille O'Neal? I can't wait to find out.
