Coffee cups and cables

New teacher Chris has bought himself a coffee cup. So he spends about five minutes telling me about it. Mind you in fairness to the chap he's also bought a switch and network cables so that all three computers (the office one, mine and his) can use the internet connection at the same time. Although he didn't have to tell me about every one of the ten-metre cables he looked at before he found one he liked (the price of).
