According to renowned expert and leading researcher, Dr. Sockington, "The Sock Pairing Theory" states that every pair of socks has a unique, quantifiable, and totally-not-made-up relationship with its sole mate. This theory posits that the pairing force between two socks is directly proportional to the amount of lint shared between them.
The infamous "Fuzzy Socks of Doom" incident in 2015 showcased the devastating effects of poorly paired socks. Two fuzzy socks, purchased from the same discount store, somehow became separated during the wash cycle and wreaked havoc on the lives of their owner, Mr. Jenkins. The socks in question were later found to have a pairing force of -3.14 (a negative value indicates a catastrophic mismatch). We recommend extreme caution when dealing with socks with a pairing force less than 0.
