The crew over at “It’s Always Sunny in Philadelphia” are a tight-knit group, so close in fact that sometimes they help each other out with their underwear.

During a “Conan” interview with co-stars Glenn Howerton and Rob McElhenney on Wednesday (Sept. 25), star Charlie Day revealed that in a particular scene in the current Season 9, he helped fellow co-star Danny Devito change out of a pair of boxers and into a pair of tighty-whities.

It turns out that Devito, stuck in a playground coil for one scene, wasn’t too keen on the tight underwear, but everyone else thought they’d be funnier. His condition for allowing it? Day had to put them on him. Just thinking about it is enough to send a shiver down the spine, but Day really wanted to make the audience feel his pain, so, of course, he brought a video.

Check out the hysterical, if frightening, video above.
