The line comes from Forrest Gump, the 1994 film directed by Robert Zemeckis and starring Tom Hanks in the title role. Forrest says it to Jenny while explaining that even though he may not be smart, he knows what love is. The film was a major cultural hit and won the Academy Award for Best Picture, which helped its dialogue enter everyday language. Decades later the quote is clipped and reused as a reaction sound for moments of honest confusion or humility.
About this sound
Forrest Gump says I'm not a smart man in this famous movie quote, often used for self deprecating humor and humble reaction moments online today.
This is Tom Hanks as Forrest Gump delivering his humble line I'm not a smart man in a soft, sincere Southern accent. The delivery is slow, earnest and completely without irony, which is what makes it land so well. Forrest is not making a joke, he is stating what he believes about himself before explaining that he still understands love. Played on its own, the clip feels disarming and a little sad, but in edits it becomes instantly funny because the honesty cuts through any overconfident setup that came before it.
