What is Worse than Death?

Can you believe that no one in the process of making this commercial realized that saying "dies, or even worse, they hurt others" was being said in reverse?

Spell-Check is Worth 1,000 Dollars!

Now some (the company) may consider this as free advertising, OR, you could consider it as a warning... as you can clearly see that they are offering tutoring in ENGLISH and math, and helping people get ready and better prepared to take the SAT, etc., yet they, themselves, are unable to spell the word guaranteed correctly on their poster for their class. Yes, they, and the company who made the sign, actually put the words together, printed it, checked it, and posted the sign on the street corner. Never during this process did anyone catch that word, and if so, figured that it would be bad publicity for the teaching of English, of all subjects!
