This is a cool Thanksgiving game I found off www.familyfun.com:
Name that turkey tune
Your guests won't mind singing for their supper with this musical amusement. Have them take turns crooning familiar songs, replacing all the lyrics with the word gobble. Choose a category for each round (Christmas carols, Beatles tunes, or TV theme songs, for example) and see who among the nonwarbling guests can be the first to make out each melody.
