Er ... you don't know "Joy to the World"? It's one of the most famous Christmas songs.
Here (but careful - there's a lot of unnecessary drum business).
As for "Like a Surgeon" ... sure, Weird Al did it really well. (I was thinking of "Like a Verger", but couldn't think two seconds without singing "Cuttin' for the very first time!")
How about ... "Fad" (parody of "Bad" by Michael Jackson) ... about, well, really -- any fad you like. Or fads. Troll dolls, selfie sticks, reality TV ... you name it -- it's like shooting fish in a barrel.
On a similar note ... "Cat" (parody of "Fat") ... all about your favourite feline friend!
Or, maybe ... *thinks* Just for the hero in QfG5!
"Your Heroscope For Today"
(parody of "Your Horoscope For Today" by "Weird Al" Yankovic)
AQUARIUS!
Excitement is in your future when you are just the one to battle a dragon - red!
It will be quite exciting if you think that baking in chainmail will bring you joy
PISCES!
Try to avoid any Cancers and Libras who-o are good assassins
Those harem pants suit you quite well, no matter what Ferrari or Ugarte say
ARIES!
The look on your face will be priceless when Arestes sends you to steal a trireme from Andre
If he says "Just kidding" give him the bird, then give a wedgie to Fenrus too
TAURUS!
You will go on quests forever more - you can't do anything about it
And I predict tomorrow you'll wake up, rush about on a quest and then go back to sleep
Chorus:
That's your heroscope for todayy-yay-yay-yay-yay-yay
That's your heroscope for today
That's your heroscope for todayy-yay-yay-yay-yay-yay
That's your heroscope for today
GEMINI!
Your good ol' breakfast will be ruined once again by Gnome Ann's bungling clown cooks
Your exploits will run into trouble when Hesperians shoot a crossbow bolt through your head
CANCER!
The position of Saturn implies that you should spend the rest of your cash on papier-mache!
Try not to fall upon your sharp and shiny sword while fighting a monster too...
LEO!
Now is not a good time to go depositing cash into the bank that Sam built, oh no
Eat a plate of Marrak's PJ pizza, then wash it down with a gallon of water to boot
VIRGO!
All Virgos are extremely gracious, gifted, bright and quick - except for you!
Expect a big surprise today, when Ferrari sticks your head upon a big ol' spear
Chorus:
That's your heroscope for todayy-yay-yay-yay-yay-yay
That's your heroscope for today
That's your heroscope for todayy-yay-yay-yay-yay-yay
That's your heroscope for today
Now you may think that these are counterfeit
or at the very least a little phony calculations and big prophecies
'cos after all the planets spin around the sun at all times,
therefore there could be no moment when they speak of only you,
but let me give an affirmation that these prophecies and guesses
were all reasoned and concluded by the good Doctor Pretorius,
so you would have to be a little stupid not to comprehend
that of these divinations, they are all completely true.
Where was I?
LIBRA!
Some help from Rajah is just around the corner - for everybody else except for you
Potions are the very best medicine, remember that when the assassin kills next week
SCORPIO!
Get ready for an unexpected trip when you fall screaming into Mount Draconis
Work a little bit harder on improving your balance and poise, you clumsy fool
SAGITTARIUS!
All your clothes are getting malodorous... WASH THEM!
Note down all those honour speeches that Rakeesh gave you while a-sitting on his rock
CAPRICORN!
The stars say that Magnum's a thrilling and brilliant person... but you know they're lying
If I were you, I'd lock my doors and windows and never never never never never let him in again
Chorus:
That's your heroscope for todayy-yay-yay-yay-yay-yay
That's your heroscope for today
That's your heroscope for todayy-yay-yay-yay-yay-yay
That's your heroscope for today
That's your heroscope for todayy-yay-yay-yay-yay-yay
That's your heroscope for today
That's your heroscope for todayy-yay-yay-yay-yay-yay
That's your heroscope for today!
