First the German went and it fell to 15 stories and they all were impressed.

Then the Australian went and he floped it out and his fell to 30 stories and the other two were impressed.

Then the last, the American went and as soon as he floped it out he started wiggling his waist and the other two said "What are you doing?"

He said "doging traffic."
