My little cousin thought he could hide a cable run behind the couch with duct tape
He wrapped the whole coax line in silver tape and stuck it to the wall, but it peeled off and took some paint with it. I had to redo the run and explain why we use proper clips, not just tape. His mom was mad about the wall, but we all cracked up at his 'invention'. Now I bring extra clips to family visits just in case, lol.
