While I'm at it, I might as well mention how we do it in the Army, where the man is Officers.

Keep in mind, we are required to salute officers on post. So here's how we mess with them.

1) When leading a formation, if an officer approaches, I have everyone fall into a single-file line with 7-8 paces between each person. The reasoning is, the requirement is that you salute the officer at 6 paces, and he (if he's not a jackass) returns your salute. So, when 225 guys walk by with 8 paces between each one, you can imagine how the officer's arm might get tired pretty quick, going up and down between each soldier.

The same trick can be performed by making 6 or 7 soldiers walk in a circle around said officer.

I actually have officers that move to the other side of the street now when they see me leading formations ;)

2) When an officer is trying to be avoidant, I make the formation double-time to his location, and repeat step 1. It's pretty funny.

3) Say something totally off the wall. You're supposed to give "The greeting of the day". We'll say something like "Look out behind you, sir", or "Sorry about your loss, sir". The reactions can be pretty funny.
