The clip comes from the US version of The Office, in the season five episode Frame Toby from 2008, when Michael Scott discovers that Toby Flenderson has returned from Costa Rica and is working in the annex again. Steve Carell's escalating scream was clipped first as a reaction GIF with captions, then as audio on its own. Because Toby represents everything Michael hates for no real reason, the overreaction became shorthand online for horror at an unwanted return, and it still circulates in edits, streams and group chats.
