For all I know, the TalkingSanta iPhone app has been around for years, and it's come and gone as the app dujour for 12-year olds. But my nephew Bill just showed it to me, and I've spent happy hours making Santa say outrageous things and burping. But as a journalist, I figured Santa deserved equal time. I especially wanted to know the most common thing people have him say. Turns out, some people are trying to break up Mr and Mrs Claus.
