We all remember the awkward circle at the beginning of every Phys ed. class where the teacher would stand in the middle, and we would all reluctantly copy them whilst they would bend into odd positions and count aloud for a period of time. Every now and then, someone would let out a "passing of wind" sound where the teacher would turn around sternly, and everyone would be holding in their laughter. Ahh, the good old days of static stretching.
