Yes, crap does happens to the best of us.
Kinda embarrassed to admit this but what the heck.
Last year I put on my winter tires like I always do in my shop. Have a set mounted to wheels so not a big deal. Needless to say this is not my daily job however during the install I was interrupted and had to do other stuff a few times before I was able to complete the work. Left the shop and about a kilometre away I heard a small clunk, clunk sound. Stopped the car and checked the lugs. Yep, with all the interruptions I skipped torquing one wheel. Put the summers on both my wife's car and mine not too long ago. This time I triple checked the nuts.
