I remembered the story of a pigeon on a bicycle in the summer.

xxx: The story happened in the summer when I was riding a bike trail. On the way I followed, a not frightened flock of pigeons formed, for which the rapidly approaching object did not pose a threat. In a meter before contact, the herd decides to leave its current habitat. The lack of analytical thinking did not allow to calculate the trajectory of the flight, or over them the desire to commit suicide prevailed. Thus, one of the members of this herd inevitably collided with my leg and accelerated, according to Newton's second law. As a result, this angry bird headed toward a fortification structure called a bench. Well, it is believed that on a beautiful summer evening on the bench there were several modmuazels, the density of which on this bench was such that it did not allow the feathered projectile to fly past. In spite of Newton’s pedal laws, I started to rotate faster.
