Rhett & Link have never been afraid to put the adage “you are what you eat” to the test. 

But, long before Tom Hanks, Hugh Jackman, Jason Kelce and Kylie Kelce and more tested their tastebuds on the Mythical stage, Rhett McLaughlin and Link Neal were releasing comedy songs and pulling out all the stops for their growing online audience.

“We definitely do put ourselves out there,” Link told E! News in an exclusive interview. “And I mean way out there.”

Let’s talk about that: From getting vasectomies on camera to coating themselves in marshmallow fluff, the life-long best friends have given fans a front row seat to their journey—and shenanigans—since they launched their first YouTube channel in 2006.

“We've seen ourselves in so many compromising situations,” Rhett explained. “If we were constantly judging every single thing that we did, we would never have made as much content as we have.”

These days, their empire includes their daily show Good Mythical Morning and cooking show Mythical Kitchen starring Mythical Chef Josh Schere, as well as online series Wonderhole, content subscription service Mythical Society and several podcasts. The pair now foray back onto the literary scene—after previously releasing a cookbook, novel and Book of Mythicality—with their new children’s book Spaghetti Head & Chicken Fingers. 

“A lot of kids are picky,” Rhett told E!. “So we knew that this would be something that parents could relate to.”

The story follows Lumo and Saffy, two kids who see first hand the meaning of “you are what you eat” when they transform into their favorite foods after a magic lightning storm.

Buttered noodles were a staple for Rhett’s kids—he is dad to Sheperd, 17, and Locke, 22, with his wife Jessie—growing up, much like their character Saffy whose hair turns to spaghetti in the book.
