What's the obession with the number 143?

1) apparently it PRE DATES the pager era and started with Mr Roger's

On Mister Rogers' Neighborhood: "Transformations", 143 is used to mean "I love you". 1 meaning I for 1 letter, 4 meaning Love for the 4 letters, and 3 meaning You for the 3 letters. Reportedly, Fred Rogers maintained his weight at exactly 143 pounds for the last thirty years of his life, and associated the number with the phrase "I love you"^[1]

2) it's also the The atomic number of Unquadtrium, a temporary chemical element^[6]

3) I like this one the most :

143 is the sum of seven consecutive primes (11 + 13 + 17 + 19 + 23 + 29 + 31). But this number is never the sum of an integer and its base 10 digits, making it a self number.

Every positive integer is the sum of at most 143 seventh powers (see Waring's problem).

143 is the difference in the first exception to the pattern shown below:

3 2 + 4 2 = 5 2
3 3 + 4 3 + 5 3 = 6 3
3 4 + 4 4 + 5 4 + 6 4 = 7 4 − 143 .
