The line is linked to Paul Rudd's Celery Man appearance on Tim and Eric Awesome Show, Great Job!, where Rudd plays an odd character in a celery costume delivering strange, serious-sounding lines. The sketch became a cult favourite among fans of absurdist comedy, and short clips from it were shared online as reaction sounds. Oyster smiling survived because its plain delivery makes it easy to drop into unrelated videos, where the mismatch between the calm voice and the ridiculous image creates the joke.
