"The Simpsons" pays tribute to rotoscoping -- or, as Lisa calls it, "a noble experiment that failed" -- in the couch gag for Sunday's episode "Barthood." Watch a sneak peek below.

It's Bart's coming-of-age story, a la "Boyhood," chronicling his life from 6 years old to his time as an adult young man, and exploring his tense relationship with Homer, an overly uncaring version of himself and Lisa, who overshadows him at every step along the way.

"Barthood" airs Sunday at 8 p.m. ET/PT on Fox.
