DH and I both love Christmas Vacation, and we quote it all the time, too. DH owns his own electrical contracting business (his "side" job) and if I hear him on the phone with a customer describing something about needing 220V, I always have to chime in with "220..221...whatever it takes".
I actually saw a set of the moose eggnog glasses for sale on
amazon. If they weren't $60, I would totally buy them!
