Wearing dirty socks
In college a couple of years ago, one of my friends bet me $100 that I couldn't wear a pair of socks for one month without changing them to a fresh pair. I happily took that bet because I knew that I had on several occasions worn my socks that long (and longer) just on my own for the H*** of it. So I took the bet and literally blew the bet out of the water by setting my own personal record by wearing the socks for a whopping 97 DAYS before changing them out! In other words, more than 3 times the required amount of time to win the bet!
Now, that was about 5 years ago and I have decided to break my own personal record. So, on September 1st I began wearing a pair of socks. As of this writing, it is now December 21st and I am still wearing the socks! I have now broken my college record by about 2 weeks. But I have decided to take it farther and will continue to wear the socks. I have set my new goal for March 1st as the day that I will finally change socks, thereby setting a new record of SIX MONTHS! Have NO DOUBT that I will reach my record!
