You have to feel sorry for Peter Sissons. He's live on BBC News 24, a car has crashed into Glasgow Airport, and he's got an eyewitness on the line. Except the eyewitness seems to be having trouble hearing, and then a completely different voice appears in its place. Listen to Peter's somewhat bemused reaction and remember - all this is live on air:

I don't know why I should be laughing, given this happens to the likes of us far more frequently than it'll ever happen to Peter Sissons. Later on I'll present to you a truly mad five minutes from David's show earlier today, where we ran a competition in which contestants had to name all the train operating companies in the UK. It gets to the point where we have people yelling the word 'cuff links!' down the line at us.

(This is the 'second song of Sissons' since the first one was last year.)
