There used to be a very funny show on Oz TV called Full Frontal, a series of (usually unrelated )skits each week. One which I tell people about fairly regularly is the sleazy-looking, show-off, yuppie type talking long and loudly on his mobile phone at the bar, right near the TV set. Suddenly his real mobile phone rings and it turns out he has been talking in a one-sided, pretend conversation on the TV remote control.Might lose a bit in translation, but the actors in the show are all wizards at minimalist comedy based on characterisation & body language etc.
I used to mimic people with the early mobile phones who would stand out in the street (poor reception anywhere but in the street) with their arm up in the air and a look on their face that said "Look at me - I have /can afford a mobile phone".
I don't give my number out, don't turn it on unless I'm expecting a pre-arranged call or if I want to make a call, which is rare, and usually only in emergencies. Handy things if you control it and don't let it, and other people, control you.
