Many years ago when I was a wee lad, my friends had 2 walkie talkies, we were out in some fields or something, and we found that other people were talking on the same channel, it was a girl and her mum. Cue the relentless swearing and 'MCing' down the walkie talkie. The woman was like 'DO YOU KNOW IT IS AN OFFENCE TO SWEAR OVER THE AIRWAVES' we were laughing our butts off.
