A Worm Student tries to pass a test in biology. Student is bad in sciences. His glance is wandering through the audience helpless. Eventually he sees a flower pot. On the flower sits an earthworm. *Herr Professor,* - says the student, - *I bet that I stick this worm into the ground!* Professor takes up the challenge. Student calmly takes the worm, squeezes some glue on it, blows on him - a worm freezes - student gently sticks it into the ground. Herr Professor says: *Well, you've passed the test...* On the next day student encounters the professor in the hallway. Professor hands him an envelope with a hundred dollar bill. The student refused. Little confused professor says - *Keep it, - it's not from me, it's from my wife...*
