Either you mis-heard him or he was making a joke based on Tom Hanks' appearance on Saturday Night Live about twenty-something years ago. Hanks played Garth's cousin (Wayne & Garth of the "Wayne's World" skit), who was a roadie for Aerosmith.

He set up the mics and checked them by saying, "Testing...Testing...1...2...sibilance, sibilance..."

Sibilance is: http://en.wikipedia.org/wiki/Sibilant_consonant

Actually, it's a pretty good way to test a mic--the word "Sibilance" has so many plosives and frictives that you can tell if the mic is going to make you sound like Sylvester the Cat (Sthufferin' Sthuccatash!") when you say "s" or "p" sounds.

Since you are a teenaged Australian, I have no idea if you have ever seen the old Saturday Night Live skits...the time of Hartman, Myers, Carvey, Spade, Miller, Dunn, Hooks, Rock, Farley...greatness.

Testies, testies, one, two.........three?
