Frank Black (former Pixies frontman/songwriter) wrote a song called “The Swimmer” on his album Dog in the Sand, containing the rhyme:
Amazingly, he manages to make these two lines work in the midst of a song that completely fucking rocks.
My first thoughts were of Pink Floyd,
Wish you were here
*And did they get you to trade your heroes for ghosts?
Hot ashes for trees?
Hot air for a cool breeze?
Cold comfort for change?
And did you exchange a walk on part in the war for a lead role in a cage?
*
Southhampton Dock
She stands upon Southampton Dock
with her handkerchief
and her summer frock
clings to her wet body in the rain
In quiet desperation knuckles
White upon the slippery reins
She bravely waves the boys goodbye again
Well basically you’d have to post the whole song. My Lehrer contribution (not a couplet) from the Elements (obviously)
Argon Krypton Neon Raydon Xenon Zinc and Rhodium and
Chlorine Carbon Cobolt Copper Tungsten Tin and Sodium
Cannot. . . Resist. . . Poisoning Pidgeons in the Park
When they see us coming the birdies all try’n’hide
But they still go for peanuts when coated in cyanide
And old Robyn Hitchcock song, again not a couplet (sorry)
All aboard - Brenda’s iron sledge
All aboard - Brenda’s iron sledge
Please don’t call me Reg
It’s not my name
Maybe you had to be there.
from Forbidden Broadway’s Ethel Merman parody:
You don’t need amplifying
You’ll be loud as a lion
Be like me, use your dia-
phram.
Take that thing off your forehead
It looks like a nuke warhead
And you sound sheepish as a lamb.
Using “diaphram” as a double rhyme for lion and lamb is pure genius.
From Company, courtesy of Stephen Sondheim:
When a person’s personality is personable
He shouldn’t ought to sit like a lump.
It’s harder than a matador coercin’ a bull
To try to get you off of your rump.

[DRE]What’chu say? [EMINEM]What’s wrong? Didn’t think I’d remember?
[DRE]I’ma kill you motherfucker! [EMINEM]Uhhh-aahh! Temper temper!
Mr. Dre? Mr. N.W.A.?
Mr. AK comin’ straight outta Compton y’all better make way?
Eminem/Dr Dre - Guilty Conscience
From Rent “You’ll See”
You want to produce films and write songs?/You need a place to do it
It’s what we always dreamed about/Think twice before you pooh-pooh it
Say what you want about Eminem, in his heyday he was damn creative.
I don’t have that bad of a mouth, do I? Fuck, shit, ass, bitch, cunt, shoo-be-dee-doo-wop?
Skippity-bee-bop, a’Christopher Reeves, Sonny Bono, skis, horses, and hittin’ some trees
Easily my all time favorite rap lyrics!
I submit the following from The Bloodhound Gang:
From Bad Touch:
From Take the Long Way Home:
Ah, rap.
From Mack 10’s Connected for life…
To all the bitches that think they bootylicious
I think they nutritious
I think they do dishes
Get’s ya right there, don’t it? 
“Predictable,” from Pete Townshend’s “Psychoderelict” album:
As does,
She’s addicted
To what my dick did.
from one of the artists on the juice soundtrack, but I hate to google it at work!!
Because I remain obsessed with the Wicked OCR,
A triplet/couplet combination, from Popular:
Don’t be offended by my frank analysis,
think of it as personality dialysis,
now that i’ve chosen to become a pal, a sis-
ter and advisor,
there’s nobody wiser!
Speaking of The Decemberists, how about their song “The Infanta”:
“And above all this folderol
On a bed made of chaparral
She is laid, a coronal placed on her brow.”
There’s a lot more–some of the other interesting couples include palanquin with elephant, pachyderm with passenger’d, and coach-and-fours with King of Moors.
Their song “The Legionnaire’s Lament” has good rhymes, too:
"I’m a legionnaire,
camel in disrepair,
hoping for a frigid air
to come passing by.
I am on reprieve,
lacking my joie de vivre,
missing my gay Paris [pronounced in the French manner]
in this desert dry.
[snip]
Medicating in the sun,
pinched doses of laudanum,
longing for the old fecund-
ity of my homeland.
Curses to this mirage!
A bottle of ancient Shiraz,
a smattering of distant applause
is ringing in my ears."
Lyrics by Stephen Schwartz, who has an incredible talent for writing internal rhymes. My favorite is from “Mass”
There are people who doubt it.
There are people who doubt it and shout it out loud.
There are local vocal yokels who we know collect a crowd.
“Local Vocal Yokels.”
Believe it or not, my entry is from Pete Seeger (et. al.) with new lyrics to “Old Time Religion”
(It helps with a New England accent)
Let us pray just like Egyptians
Build pyramids to put our crypts in
Fill subways with inscriptions
and that’s good enough for me
Let us pray to dear old Budda
For their is no one cuter
He comes in plaster, wood or pewter,
and that’s good enough for me
Let us pray to Zarathustra
Pray just like they used to
I’m a Zarathustra booster
and that’s good enough for me! *
don’t really care for rap but I gotta mention from Ice Cube/NWA, “Express Yourself”:
Movin like a tortoise/
Full of Rigor Mortis
Eminem has some really amazing internal rhymes.
One of my favorites:
“I guess that’s the gist of it/
The parents are pissed, but the kids love it”
He puts a little emphasis on the ‘of’ in the first line, making it just an excellent couplet.
