The line parodies Only You Can Prevent Forest Fires, the long running Smokey Bear wildfire prevention slogan introduced in the United States in 1944. The original campaign became one of the most recognised public service messages in American culture, with the wording later updated to refer to wildfires. By changing one key word from prevent to start, this version turns a responsible warning into an absurd instruction. Online, that simple reversal is shared as a reaction sound for fire related jokes, camping clips and deliberately bad decisions.
