Since it is Christmas how about lines from carols? Everyone must know the first lines of carols - but how about the first line of the second verse? Tape some songs - different eras and they have to give the title of the song or the singer. Tape the themes from some adverts and guess the product. You could do the same for TV programmes. Much more interesting than just reading out questions - and they go further as it takes longer to play the tape than it does to read a question!
