'Game of Thrones' Stars Hilariously Answer Questions From Confused Fans Who Call Hotline

This clip is a must for 'GoT' fans!

Got some nagging Game of Thrones questions? The solution has arrived! Sort of.

On Monday, Jimmy Kimmel Live! released a hilarious new clip featuring an ad for Game of Phones, a (not at all real) hotline for fans of the hit HBO show who aren't quite clear on some things within the sprawling story. But the best part is that it's manned by cast members!

The first up is Sophie Turner, aka Sansa Stark, who's picking through a giant container of Skittles while fielding the question: "Who killed King Joffrey?"

"No one did, it turned out to be a bad clam," he explains to the inquisitive caller. "Remember, you have to tap the shells to make sure they're alive before you cook them. That's clam 101."

Next up is Cersei Lannister herself, Lena Headey, who's also cooped up in a cubicle answering questions on the line. She's asked, "I have a crush on my brother, what should I do?"

"Nothing," she says beside a photo of Jaime Lannister (Nikolaj Coster-Waldau) in a heart-shaped frame. "It's illegal and immoral to act on those feelings... On the other hand, if he's hot, go for it."

The actor behind Samwell Tarley (John Bradley) was also answering nagging questions, including some that didn't turn out to be Game of Thrones-related. 

"I think I have greyscale," a caller explains to him, to which he replies, "Are your genitals swollen and tender?" When they confirm that they are, he adds, "That's chlamydia."

The clever sketch also features cameos from some actors who didn't quite make it to the end of the beloved show, like Ramsey Bolton (Iwan Rheon) and Hodor (Kristian Nairn), doing their best to help strangers. Arya Stark (Maisie Williams) is even on hand to explain face-swapping as a Faceless Man!

This incredible clip arrived just one day after season 8 premiered, featuring a few key moments for fans including (spoilers!) the moment when Sam reveals to Jon Snow (Kit Harington) that, although he gave up being King in the North, he is still royalty -- heir to the throne of the seven kingdoms, in fact. 

ET spoke with Bradley earlier this month about the monumental moment, which he explains was always Sam's job to do.

“If Jon is gonna find out that key piece of information, he'd rather hear it from Sam than anybody else because he knows that Sam is the person who will be doing it for the right reasons and he's not got an agenda.” Bradley explained. “He's not trying to cause trouble. He's just telling him because he feels he needs to know."

Game of Thrones airs Sundays at 9 p.m. PST on HBO.
