That thing where you put on a fresh pair of socks and one has a hole so you think well I went to all that trouble to pull it on, this will be your last day little buddy, I’ll just throw it away after I wear it today.
Last chance underwear happen now and again as well but I guess it depends on where the hole is.
Apparently Darn Tough socks have lifetime warranties. I have 4-5 socks knotted up out of 10 that got big toe holes. They’ll get sent in sometime…
