I have discovered my DREAM Xmas Display thanks to a commercial that was on the other night for some Christmas thingee in the Tacoma dome or some-such with "The Singing Nativity".

So my dream is an animatronic Nativity, ala "Chuck E. Cheese", all singing "Grandma Got Run Over By A Reindeer". And at the end of the song, when they say "Sing it, graaaandpaaaa..." and then the deep barritone chimes in with the chorus? That's when the Baby Jesus will bolt up-right in his bassinett and start singing along :)
