Three women are told they'll get everything they want if they tell the truth, but the result is a knee-slapper

One day, three young women found a magical mirror. If they spoke the truth to it, they would be granted many incredible gifts, but if they lied, they'd vanish from existence forever.

The redhead stepped forward and said, "I think I'm the smartest one." 

Just like magic, she suddenly got a diploma and a scholarship and was accepted into all the top universities in the world. 

The brunette then said, "I think I'm the prettiest one." 

Then she got a Corvette, mansion, a good looking boyfriend, and a lot of money. 

Finally the blonde stepped forward, and after a few seconds, started, "I think..." 

Suddenly, poof– she disappeared.
