Cricket Whistle

Spent too long examining the moral dimensions of a particular Star Trek character, so, no BattleTech this week. Instead, here's two ways to sound like a cricket:

1. You know that thing in the back of your throat, that you use to gargle, and to make the Predator clicking noise? You know how most people whistle by exhaling through pursed lips? Trill that thing while whistling. (This doesn't work very well if your throat is dry.)
2. If you can whistle by inhaling through pursed lips, do so with a little spit on your tongue. (My preferred method.)

It's a fun gag. Games occasionally have quiet pauses (a joke falls flat, or the group is hesitating indecisively) where a chirp can get a laugh.
