My two daughters sometimes change my ringtone, then ring me up for a laugh. They got me last Christmas (which is why I've suddenly thought of this) by switching it to Away In A Manger. I was at my desk, slagging off the ringtone and it's cursed owner for a fair while before I realised it was my phone ringing.

Before that, their best was perhaps recording the words: "I'm gay, I'm ever-so gay", making that the ringtone and then phoning me on the train.

Any better ones?

LMAO!!

So you succeeded in passing on your good sense of humour... got to live with the consequences .
