I dropped my grandfather's straight razor at a barber to have it sharpened. When I picked it up, the barber asked what I planned to do with it. "Shave with it" I said. He got a big grin on his face when he handed it to me and he said "Good luck with that."
Scariest shave ever! I then knew why my grandfather took so long to shave, and why beards were so popular back then.
