A blonde walked into her final exam very nervous. But when she received the test, she was relieved to find out that it was a True or False exam. Immediately, she reached into her purse and pulled out a coin. Each time she flipped the coin she would write down an answer. "What are you doing?" the professor asked her. "I'm figuring out the answers," the blonde replied.

To this, the professor just rolled his eyes and looked away. When she was done, the professor announced that there were five minutes left to go. "Oh my god!" she said in an excited voice, and started to flip the coin as fast as possible.
