More importantly, I know how to direct someone else to do the gardening now, heh heh heh.  
I think I can still probably field strip and clean most of my arsenal without looking, but I am probably a lot slower doing it these days.  
I used to do Amazing Grace to the tune of Gilligan's Island while in the church band.  I got a wicked scowl from the pastor, but I busted up the congregation pretty good.  I've since learned there's a more appropriate time and place for such antics than right before the sermon.
Try it out and you'll see, the tune actually fits the words pretty darn good.
