“Don’t follow me. I’m lost, too!” is a popular bumpber sticker.  “Don’t Follow Me. I’m Lost Too!” was scribbled on the back of a jeep in 1944. The saying became popular in the 1950s, when it was one of the earliest bumper sticker sayings.
 
“Don’t follow me. I’m lost, too!” was used in a religious message to the spiritually lost in 1953.
