I think this is the last of the Christmas song parodies.
This one also parodies the love most children have
for "potty humor" (a love shared by many adults,
although they won't admit it.) This is a parody of
the children's Christmas song Up on the Housetop...
and if you pay attention, you'll find allusions to
an uncomplimentary name for chipped beef and
a favorite Christmas poem by Clement Moore.
I must admit, I'm rather proud of this one.
Poop on the housetop –
Eight busy reindeer
Out all night –
It’s on the shingles
Where they alight!
Ho ho ho, you better know
Ho ho ho, they’re gonna go!
Poop on the housetop;
It’s no trick –
You’ve had a visit from
Old Saint Nick!
