Emoticarolers is the kind of thing that should be too silly for me to be into, and yet, here I am, powerless to their cute yellow faces and midi voices (or maybe I was just swayed by the fact that the parody lyrics the site offered me for "Deck the Halls" were "Deck the Halls With Flat Screen TVs").
You pick four carolers and then a classic holiday song (original or parody lyrics), and then you can send around your custom "card."
It's way less annoying than strangers showing up to your door singing while you awkwardly stand there bobbing your head.
