Finding Nemo is a 2003 Pixar animated film, and Bruce is the great white shark who leads a support group of sharks trying not to eat fish. Voiced by Barry Humphries, Bruce appears friendly until he smells blood from Dory during a meeting, which triggers his instincts. The short reaction line became popular in edits and soundboards because it isolates that sudden change from control to craving. Online, creators reuse it for food reveals and temptation jokes without needing the full underwater scene for context.
