Now use it to empty the trash bin beside your desk.
So far so good?
First, just say "bang" into the air.
Ok, now hold the bin in two hands.
Now.. hold the bin in front of your face.
(Open end towards your face!)
K, say "bang" again.
That's called "amplification".
Say it with me... "ammm - pli - fi - ca - shun"
This is what I hate about take'en
a crap in a public wash room.
