Bicycle Drill

The physical training instructor was drilling a platoon of soldiers.

- I want every man to lie on his back, put his legs in the air and move them as though he were riding a bicycle - he explained. Now begin!

After a few minutes, one of the men stopped.

- Why did you stop. Smith? - demanded the officer.

- If you please, sir - said Smith - I'm freewheeling for a while.
