Rhymes with Hippopotamus

Hippopotamus
Let's get off the bus
Ap Calculus
Stratocumulus
Then it's Tratorous
In the Hindu Kush
Quite Calamitous
On the auto-bus
If I must, I Must
Eating Bouef-au-jus
God it's Enormous
Simply Marvelous
Captain Fabulous
A Stink Egregious
Closets Full of Dust
Playing songs by Rush
Closing Toys-R-Us
Flowing Riotous
Gotta Gun it, Gus
How's that Helping Us?
Got that Magic Touch
There's a Kind of Hush
In a Country House
I'd say Minus/Plus
If it's Good for Us
Sitting Close to us
Silver Member Plus
Boy she Likes to Gush
There's Homogenous
Latitudinous
Duck Billed Platypus
Largely out of Touch
Touch a Tiny Tush
He's Innocuous
We'll Declare a Loss
Coolly Wondrous
Disingenuous
Misadventurous
Far and Nebulous
So Nefarious
Not Industrious
Veard and a Mustache
It's Malodorous
Hafta readjust
Muy Gelatinous
Multidinuous
City Detritus
Lofty Humonguous
Ripe and Rich Bulbous
Clever Octopus
Like a Pot of Mush
Not Analogous
Serendipitous
Little Wandering Mouse
How Voluminous
Hit the Closing Rish
