Tell you what, Lurch. Get yourself a big wreath. REAL big, with lights and all that mess, and hang it on your grill. Get you some red shoe polish and write "Merry Christmas" or "Happy Birthday, Jesus" or whatever on your rear window. And get a santa hat, too. A BIG ONE. And wherever you go, from now until the day after christmas wear the hat while you drive.
For bonus points, drive around in your decked-out car, with your hat on through all the rich neighborhoods in your area and check out the lights.
WHEN YOU GET HOME, LIGHT A ROARING FIRE AND GET DRUNK ON EGG NOG. That's important.
