Molybdenum

42
The atomic number of molybdenum.  "Ya can't get to molybdenum if ya start with Molly." gaffs John Twist.

42
The nominal mass of one rare isotope of Calcium.  Trumpery if there ever was such a thing.

42
It is nearly impossible to see the number without a reference to The Hitchhikers Guide to the Galaxy as 42 is the "Answer to the Ultimate Question of Life, The Universe, and Everything."  It is a bit sad, but I haven't actually read the entire series of books.  I think I'm supposed to like Sci Fi, but I really don't.

42
The angle rounded to whole degrees for which a rainbow appears (yeah, that was from Wikipedia).

42
The number of gallons of oil in a Barrel (kind of political).

"Rule Forty-two. All persons more than a mile high to leave the court."
Everybody looked at Alice.
"I'm not a mile high," said Alice.
"You are," said the King.
"Nearly two miles high," added the Queen.
"Well, I shan't go, at any rate," said Alice: "besides, that's not a regular rule: you invented it just now."
"It's the oldest rule in the book," said the King.
"Then it ought to be Number One," said Alice.

October 28 breaks the 300 days barrier for days in the year.

It is humorous at this age, to look back at the late 1970s and early 1980s when "backmasking" of music was assumed real.  To be fair, it is real as there are numerous (and obvious) uses of this often for satirical or artistic political effect, but the hysteria that surrounded this now looks almost lunatic.  The real examples of this aren't hidden, pushing evil thoughts into corruptible minds.  Think Pink Floyd's Empty Spaces and join the fan club.
Backmasking even made an entrance on the TV Show Night Court.  Some of the details are forever gone, but at the end, Judge Harry asks a Rocker accused of backmasking if his music contains hidden backward messages to which the Rocker positively admits that "Starve a cold, feed a fever." is contained reversed in one song.

The attack against music for backmasking satanic and evil messages was coupled with the ever ongoing dislike of current music by people who were my own age now.  ACDC's "Big Balls" probably has little in the way of social value, but is frankly more humorous than anything else.  I'm not a fan of "rap" which has rebranded itself as "hiphop" but "Damn it Feels Good to be a Gangsta" is kind of funny.  I can't help but find it exceedingly ridiculous that "Classic Rap" internet radio stations exist.  Classic Rock is perfectly plausible (and mainstream).
Looking back at being a kid in the late 1970s, our church's dislike of music made the warnings so real.  Two of the biggest targets of this were Styx and Electric Light Orchestra.  Styx was targeted largely because the name references the River in Greek Mythology that separates Heaven and Hell?  Their music was pretty tame compared to Iron Maiden.  The idea that ELO was sending satanic messages backward in their music seems even less likely - where would it go?  Both of these groups have largely stood the test of time, Styx more so than ELO and Styx seems absolutely tame in hindsight. Dennis DeYoung, a member of Styx even toured as part of Jesus Christ Superstar later.
Our church youth group taught us that KISS stood for Knights In Satan's Service.  But, what can't be cool about four guys dressed like monsters screaming rock music?

Our parents are wrong.  Not everything we learn is right.  All facts are not true.  That is what is great about getting older.

and happy birthday Julia Roberts.
