It's a beer can opener (makes a triangular hole to the side of the lid; fell out of common use due to pop-tops). I learned that one listening to KRLA's "Credibility Gap" coverage of the 1968 Presidential conventions (the correspondent was a skid-row bum with a microphone hidden in his church key).The explanation that I read is that churches are built as cheaply as possible, so the lock on the door is of such poor quality that you could open it with a beer can opener. That explanation probably dates back to when doors had actual keyholes.Somehow I get the feeling that I simply don't understand what this topic is about.Edited by dwise1, : 1968 Presidential conventions

Everybody should know that 42 is the Ultimate Answer to Life, the Universe, and Everything. But since nobody can figure out what the Ultimate Question that it answers is, we cannot make sense of the Answer.42 is also Fox Mulder's apartment number. As well as the number of times that he has watched "Plan 9 from Outer Space." A geographic location in Germany, former a wide pass near the border between East and West Germany (still a wide pass, but now in the middle of the reunited country). It was very important for NATO planning since it was deemed the most likely place that Warsaw Pact forces would invade Germany come WWIII.

There is one thing in common to all the stuff listed though and I was hoping someone would see the connection.

the clues all point to a singular answer. My best guess was 'Elvis'. Yeah, I was trying to tie Church Key to Elvis. That's the struggle.

Nipper.Very weird, I woke up this morning with it in my mind. Ignore my prior answer.....

They're all on the list.

that's right by the way but still not what is common to all the questions

When I was in high school my friends and I all thought calling a beer can opener a "church key" was a derogatory reference to the Christian churches that disapproved of alcohol consumption and also a sarcastic comment on "Christians"' who sinned all week and went to church on Sunday.I still have no clue what Jar's single right answer is.....42 should cover it.

It's a partial list of things that elicit blank stares from anyone under about 50 today.
