I like orange.
Not just for the edibility of an orange,
but because nothing rhymes with orange
except orange.

If I said "chocolate banana whipped cream sundae,"
that wouldn't rhyme with orange.

The only things that would rhyme with orange
are made-up words like Fidoelectomayoroforange,
or compound words like pseudomicro-orange.

You could try arrange,
but that's not exactly the sound of orange.
(Let's not bring up sporange.
It is a silly word not in common use like orange.)

If you have to rhyme orange,
just repeat orange.
Orange orange orange.
