I was fishing for smallies out of a boat last fall and happened upon two guys in a canoe still fishing with minnows and bobbers. As I was upstream from them I caught and released three nice crappie and as I went by them they asked what I was catching them on. I told them a clouser and they didn't have a clue. I then said it was a minnow imitation and they didn't believe me because they were fishing with real minnows and not catching anything.
I threw a clouser beside their canoe moved it a couple of feet so they could see the motion. They saw a flash and I had another crappie on. I caught and released two more downstream from them. I don't know if they were impressed or upset, but it was fun!
