Clapboard Operator operates the clapboard and calls takes while the Simpsons sit on their couch.
A director does three couch gag takes. Take one: The Simpsons first run into the living room and shatter like glass, with Santa's Little Helper walking in to look at the mess on the floor. Take two: The Simpsons run in and coalesce into a multicolored, five-headed blob. Take three: The Simpsons run in and explode on contact, with Maggie's pacifier falling onto the blackened crater (syndicated reruns use the “take one” couch gag and takes two and three are used as individual couch gags in different episodes).
