Hee hee!  CG, you're pretty much spot on with your definitions, although I noticed you left out shoo-fly pie!  (Which is a gooey, sticky mess of a dessert.  Essentially it's a molasses pie topped with a crumb topping.  Best served warm and on a day you're going to be physically busy to work it off!)

Mummers are a little more difficult to describe.  They're groups of amateur performers who dress up in wildly elaborate costumes and march in a parade on New Years Day.  There are different divisions, but the most popular are the string bands (banjos, double basses, saxophones and drums) which put on musical performances that are staged and choreographed.   There's a definite tone of irreverence to the whole thing, but it's lots of fun. 

If you google Mummers under "images", you'll get the idea, because quite frankly, words don't quite do it!
