College student pulled over by officer gets unexpected lesson

WISCONSIN -- Getting pulled over by police can be pretty stressful, but imagine you're a college student rushing to give an important class presentation when you see flashing lights in the rear view.
Luckily, this Wisconsin student didn't get a ticket. But he did get a lesson.

Dashcam video shows the officer teaching student Trevor Keeney how to tie the perfect tie knot.
Besides the knot lesson, the officer did give Trevor a written warning. And he got a 92 on that presentation.
