How long have you worn your speedo?

[PSDave]

I was at my other house a couple weeks ago (U.S.Thanksgiving) to get it packed and cleaned up for the new owners. I had a couple friends come by to help so it ended up a semi party atmosphere. Since it was warm and I have a pool we worked in swimwear so we could jump in whenever we got hot or wanted a quick break. I had pulled on a pair of royal blue nylon Speedos before they arrived on Wednesday PM and just left them on the entire 5 days they were there and we were working. I wore them during my daily shower to wash both the suit and me and then left them on to dry off. (in low humidity desert it only takes minutes) I slept in them and wore them as underwear on the one occasion we left the house. It never really occurred to me until I got back to my other house and realized the only thing I had for the laundry was that one pair of speedos, a tee shirt or three and towels.
In the past I have gone days wearing nothing but speedos - not unusual - but never gone that long without taking one pair off.
Has anyone else done that?
