Aye Carumba! "Mr. Magoo's Christmas Carol" was once parodied as "Mr. McGrew's Christmas Carol" in 2003 Simpons episode 'Tis the Fifteenth Season."
On the Fourth Day of Christmas (Thanks to Simpsons fanatics-in-crime Tom and Christine) My Casting Choice would be ...
Charles Montgomery Burns – Scrooge
Homer Simpson – Bob Cratchit
Marge Simpson – Mrs. Cratchit
Mr. Waylon Smithers - Marley's Ghost
Bleeding Gums Murphy - Ghost of Christmas Past
Moe Szyslak, Lenny Leonard, and Carl Carlson - Ghost of Christmas Present
Sideshow Bob - Ghost of Christmas Yet to Come
Edna Krabappel - Mrs Dilber
Bart Simpson - Tiny Tim
Nelson Muntz - Fred
***Four Pints of Duff Beer, Three Vats of Mead, Two Highballs of Jack Daniels, and Another Couple of Tumblers of Glenmorangie Single Malt Scotch for O'Toole, Leary, Falstaff and Barney Gumble in a Tree.***
