If you’re a fan of ABC’s darling sitcom The Middle, you know exactly what the “Brick whisper” is. It’s almost too hard to explain unless you watch, but basically, it’s a weird tick from eccentric character Brick (Atticus Shaffer), who puts his head down and repeats the last words he’s said in a creepy whisper. It sounds weird, but it’s truly funny on screen.

In this Wednesday’s episode “Hecking Order,” Glee star Chord Overstreet begins a guest stint on the show — as Brick’s new fourth grade teacher, Mr. Wilkerson — and EW has got an exclusive, behind-the-scenes video of Shaffer teaching Overstreet how to do the “Brick whisper.” “It’s a requirement for every guest star,” Shaffer tells Overstreet, of having to learn how to do his patented “whisper.” “Ray Romano, Betty White, everyone who’s on has to learn the ‘whisper.'”

Learn the “Brick whisper” by watching the cute video here:
