National Lost Sock Memorial Day

National Lost Sock Memorial Day might sound ridiculous, but it really exists, as everyone has lost a sock at least once. It’s unimaginable how socks can get lost in an apartment.

History

Socks have been around for centuries. Today, they are one of the most popular clothing items—worn by men, women, children, and even dogs. People make jokes about socks, give them as gifts, and choose quirky designs. However, the exact origins of National Lost Sock Memorial Day are unknown.

Losing socks can cause genuine confusion and frustration. Gray, black, white, red, blue socks—where do their mates go? It’s unlikely they will ever be found. To honor these lost socks, a Memorial Day was created. Some say the first such event occurred shortly after the first socks were made, when a happy owner of a warm woolen pair couldn’t find one of them after a week.
