If you haven’t figured it out by reading the other posts on this blog I’ll spell it out for you: Proofreading is just as important as “make sure the product works.”

Some typos and mistakes can be corrected, but far too many will live on forever. In case you need even more proof of that fact, I’ll summarize “The 7 Most Disastrous Typos Of All Time” as presented by Cracked.

The Source of Spinach’s Power

A 1870 German study that served as the basis for Popeye’s spinach-fueled ‘roid rage accidentally printed the decimal place for spinach’s iron content one spot too far to the right. For our non-mathematically inclined readers, that means the report claimed the vegetable had 10 times its actual amount of iron, which ended up equaling out to almost as much as red meat.

The NASA Mariner 1 Mishap

[Someone] forgot to write either the overbar or the period (or worse, both) over the R, which is apparently a big freaking deal due to rocket science being such a harsh mistress. …

Once it became clear that this software error had rendered Mariner 1 little more than an enormous Scud missile, NASA had no choice but to detonate the $80 million craft less than five minutes after launch.

Mizuho Securities Drops the Ball. Twice.

It all started when they debuted the now hilariously legendary job recruitment company J-Com Co. with the intention of offering it at 610,000 yen per share ($5,041). A typo pegged it significantly below that. At one yen per share. … [Then] it was revealed that Mizuho Securities had also offered 41 times the number of J-Com Co. shares actually in existence. …

Since do-overs are not allowed in the Tokyo Stock Exchange, Mizuho Securities was forced to watch in horror as their company hemorrhaged millions. … By the time this 24-hour snuff film was over, these twin typos cost Mizuho Securities $225 million.

The Real Bruce Wayne Sentenced to Death … Due to a Typo

In 1985, an extremely un-Batmanlike Bruce Wayne Morris was convicted of robbing and killing a man with a non-proverbial but deeply ironic stick and stone. …

The judge issued written instructions to the jury that an imprisoned Bruce Wayne would not have the possibility of making parole… and accidentally left the “not” part out. The jury, now mistakenly thinking that they had to pick between death and letting the dude maybe roam the streets again in a few years, picked death.

Bulls**t Word Added to the English Language

every now and then you will come across a word in the English dictionary whose etymology is not Greek or Latin, but freaking Typo. “Dord”, introduced to the world in 1931, is one of those words.

The Chilean Ex-Change

Engraver Pedro Urzua Lizana made a mistake in December of 2008 that slipped under the radar of all his superiors, including boss and head of the Chilean Mint Gregorio Iniguez. Under the approval of Lizana, Iniguez, and “several other employees,” the Chilean Mint misspelled the name of their own freaking country.

The Wicked Bible

To reprint the King James Bible, royal printers Robert Barker and Martin Lucas had to arrange an exact duplicate of the original book and all its 1,189 chapters, 31,101 verses and 783,137 words like Mahershalalhashbaz just begging to be misspelled. …

They amazingly eked out only one major typo: a missing word in Exodus 20:14. Unfortunately, that one missing word out of the 783,137 others turned out to be kind of an important one.

“Thou shalt commit adultery.”
