At Grandma's on Christmas day we always had the Nusery rhyme game.
Two teams
Everyone sings the alphabet
First team sings a nursery rhyme
Everyone sings alphabet
Next team sings a different nursery rhyme
......untill one team can't think of one or sings one that has been sung before.

It helped that the lights on Grandma's tree had shades with nursery rhymes painted on them. (2 of them are dangling on my tree now)
