The line comes from the American version of The Office, spoken by Michael Scott, played by Steve Carell. It appears in the 2007 season four episode “Dunder Mifflin Infinity,” during Michael and Dwight’s disastrous effort to recover gift baskets from former clients. Michael becomes fixated on missing chocolate turtles and repeatedly demands an explanation. The scene spread through reaction videos, GIFs, remixes, and social posts because its exaggerated outrage works for trivial disappointments and mysteriously missing food.
