If you click on it and take the IQ test don't give them your real cell number. They ask for it to send you the results of your "free" IQ test. Next thing you know you'll have a $9.99 recurring charge on your bill. Happened to somebody I know who should be smarter than that.
I just had a popup on my screen to take an IQ test. It stated the average IQ of a Jet fan is 137 and that the average IQ of a Dolphin fan is 135. I think I feel insulted.
