Finding a free "turn off your mobile" sound clip (movies, commercial)

[skippy upwood]

Does anyone know where I can find a free sound clip of someone saying "turn off your mobile/cell phone" for a small theatre.

It must be:

a) Verbal (since it will be played over speakers)
b) Suitable for a theatre (i.e. no swearing, easy to hear).
c) Free
d) Downloadable (or on a site like YT)

Any links would be much appreciated. All the clips I can find on YT and elsewhere are designed for movies and therefore visual in nature.

There are several on YouTube. Maybe you could just record the audio portion of the commercial or just make your own.
