I once spent a good 3-4 weeks sending random txt messages, calls, picture messages and answerphone messages to a good friend from an old PAYG phone. I think it cost me about £40-45 in the end but it was just too funny to meet up with him and have him tell me, in a genuinely paranoid way, how he keeps getting contacted by "a bloke called mick" who he has never met... Hehehe, when he finally figure it out he ignored my real attempts at communication for another couple of weeks.
