For years I have read phrases such as "the dog jumped through the tornado fencing" and then checked to see if it was divisible by three, four or five. I add the letters up (they come to 36, so three or four works)) but I then note that adding the dots from the i and j brings the total to 38 which works for none of the numbers. I have NO idea why I do that. It bugs me at time, especially when I am watching films that have subtitles. I have missed more movies that way. ("Uh, did you enjoy the movie?" "Why, yes, thank you, it was a perfect five!" Sheesh . . . .
