Reading Between the Lines

Reading Between the Fine Lines
Here's one company who was trying to bluff the consumers with claims about the gadgets.
In its brochure, it says: "Ingeniously designed for easy use, is tested by xxx".

XXX enlightened the public. She said that being tested could also mean that the product had failed the test.
The product should be certified.

So ye reader, now you know the difference between 'tested' and 'certified'.
I have a new marketing gimmick too.
If I am a school dropout, I could say, "I'm schooled in Harvard University"
If I have failed my exam, I could say, "I'm tested by so and so"
If I had work a day in a big company and got fired the next day, I could say "I have worked with IBM".
