The Wile E. Coyote couch gag is the twelfth couch gag of Season 19.
Wile E. Coyote paints a fake couch on the wall and sneaks away. The Simpson family, except for Maggie, run in to sit on the couch like normal, but they run into and get attached to the wall. Maggie runs in later, sticks out her tongue, puts her pacifier back in her mouth, and shouts, "Meep, meep!" while taking off, Road-Runner style. The remaining family members sit on the couch, except for Homer, who falls through the wall and yells, "D'oh!"
