When I was in high school, many students used the mosquito alarm as their ringtone, so the teachers wouldn't know when their phone rang. I used to hate it, because the sound was so annoying.<br><br>I just checked... I can no longer hear it. I can't even hear the noise in the background of the previous video.<br><br>I'm getting old and my body is falling apart and I don't like it :( I shouldn't feel old at almost-27!
