It’s been on my to do list for months and was the first item I added to GoogleTasks when that feature debuted.  It was on my hipster PDA for the period where I used it and it has always been on my Moleskine.  After months and possibly years of noting and forgetting, today I rolled up my sleeves and did it:  I finally applied WD-40 to the bearings on my ceiling fan so it no longer squeaks while I sleep.
