Back To School With SilencerCo

There will be a test at the end of this:

Question #1: Silencers work much like the ______

A) Trombone in an orchestra
B) Muffler on a car
C) Fish on a bicycle
D) Stink on a goat

I like when companies put effort into their videos like this.  I wonder if SilencerCo hired a professional voiceover guy for these promos, or if someone that works in the office has that buttery smooth easy to understand voice.
