"Christmas in July" joke

One Day After Christmas
It’s one day after Christmas
I’m crabby and I’m broke.
I’m so full of ham and fruitcake
I think I’m gonna croak.
It’s nice to see the relatives
I wonder when they’ll leave.
They’ve been camping in my bathroom
since early Christmas Eve.
They’re eating everything in sight
and sleeping in my bed.
I been sacked out in the basement
with my beagle, Fred.
The relatives have all gone out
and left their screaming brats.
The toilet bowl is all plugged up
and I can’t find the cat.
It’s Christmastime at my house,
the relatives are here.
They eat me out of house and home.
and drink up all my beer.
I love the decorations,
and the sleigh bells in the snow
But I wish those pesky relatives
would take their kids and go.
Those cookie crunchers fed the dog
a twenty pound rib roast.
His feet are sticking in the air
like skinny old fence posts.
Now they’re in a free-for-all,
the girls against the boys.
They’re fighting over boxes
’cause they’re bored with all their toys
My mother-in-law is snoring
in my favorite TV chair.
Those kids are stringing lights on her
and tinseling her hair
I oughta wake her up
before the fireworks begin.
But I wanna see those blue sparks fly
when they plug her in.
