That’s awesome! I particularly like the fact the record’s held by a guy called Yiannis Kouros*, who’s also done the whole Athens-Sparta-Athens run as well.
*Which isn’t surprising when you read his wikipedia bio - he holds the world records for all distances from 100 to 1000 miles!
I find that story unlikely. I’ve only seen that kind of explosive force from alkali metal reacting with water in the tv-series Brainiac, and it turns out they used actual explosives. The Mythbusters trying to replicate a McGyver alkali metal bomb showed it didn’t blow holes in a wall, even with several sticks of potassium.
You’re producing hydrogen in an open environment and you’re not producing all that much of it before it ignites. Small explosions, yes, big explosions, no.
It had all the force and terror of (junior?) high school’s permanent record, but was threatened in grammar school and maybe junior-high school.
It was a large-ish index card. It was blue.
Well, I admit that made more sense than what I expected.
James Cagney never said “You dirty rat!”.
True, I see what you’re saying. Still, I was in high school at the time, and we paid a fine, but it didn’t go away so the CRIMINAL record is the permanent record. 
Plus we did get all the “OOOOOO, you guys got BUSTED!!” in homeroom on Monday.
I think the school PR was really told more in grammar school. “Being tardy will kill your future!” Just like, “Santa Claus can see you!” So, you guys win on that one.
ANOTHER ONE: “Abner Doubleday invented baseball.” I guess we still hated Europe when that went around.
I think I read somewere that although Nero was a ‘Nutter’ he was out and about organising the fire fighting of Rome when it burned
Nero rushed back to Rome to organize a relief effort, which he paid for from his own funds
No one ever said “Beam me up Scotty”, and Mr Spock never said “It’s life Jim, but not as we know it.”
Well, except in the song Star Trekkin’:
It was used in Star Trek Animated, and Kirk said “Scotty, Beam me up” in the fourth movie.
Close enough. He had a line in The Motion Picture : : It’s life, Captain, but not life as we know it.
I think we can forgive the slight adjustment to fit the meter of the song.
I’m intrigued. What did you expect?
Apollo 13: never “Houston, we have a problem.”
Some famous person is at a dinner. During a conversation he offhandedly asks the hostess if she’d sleep with him for a million dollars. Reluctantly, she says she would.
“How about $1 then?” he asks.
“What kind of person do you think I am?” she demands, affronted.
“Madam, we’ve already established that. Now we’re negotiating on a price.”
I’ve heard this story a few times, with the famous person being either Winston Churchill or George Bernard Shaw. Which means the whole thing is probably made up.
Actually, I didn’t really expect a card as such at all; I expected more of a general record-keeping system for a specific class of offenses.
For good stories that turned out to be false, Mother Teresa must rank near the top. She might have helped somewhat but not nearly to the extent that her story was portrayed, and without nearly the compassion she was credited for having.
There’s a series of Winston Churchill / Lady Astor exchanges that are probably UL:
LA: “Mister Churchill, if you were my husband I would put poison in your tea.”
WC: “Lady Astor, I you were my wife I would drink it…”
LA: (shocked) " Mister Churchill, you are drunk!"
WC: “And you, Lady Astor, are ugly. And tomorrow, I shall be sober…”
Too Good To Be True.
Then there’s the Cherry Tree Principle:
“It’s easy to tell the truth when you are the one holding the axe.”
So, “didn’t do quite as much good as some people think” now ranks near the top as false stories go? I think you need to flesh that out a bit more if you’re going to be taken seriously. Probably in Great Debates.
And I’ve never heard the “now we’re just negotiating on a price” bit attributed to anyone in particular, just as a generic joke.
Winston Churchill’s (probably apocryphal) martini recipe, which I’ve also seen attributed to Alfred Hitchcock:
Pour dry gin into a glass, glance across the room at a bottle of vermouth, drink.
That’s nitpicking- the actual line is “Houston, we’ve had a problem”.
But Bones did say “He’s dead, Jim!” from time to time 
AND… Leonard Nimoy also said “He’s dead, Jim!” !!
(That is, Leonard Nimoy in his role as Paris on Mission Impossible, speaking to Phelps.)
But did Bones ever say “I’m a doctor, not a web programmer?”
