Take a test

The teacher is giving the students a multiple choice test. Seeing Toto juggling a coin, he asked:

- What the hell are you doing?

- Teacher, I am tossing a coin to choose the answer, if I turn, I answer is wrong, and the face is right

Toto finished the exam, he continued to roll the coins, but this time faster, he frowned:

- What else do you do, Toto?

- Teacher, I am checking the answers.

-?!
