Not rhyming

What are the English words which dont rhyme?

I know three:
Orange
Purple
Silver

Woo! I looked it up.
Haha. Talk about boredom.

Here's what it lists:
diamond, silver, purple, month, skeleton, limited, ninth, and poem.

...But I think that gelleton(jelleton? sp?!) would rhyme with skeleton...
Besides that, Haha. Check it out, it's a poetry site, and we don't even realize the word poem doesn't rhyme...
Or maybe I just can't think of any words... >_<

Oh, whoops...
I forgot to mention golf, angel, bulb, and pneumonoultramicroscopicsilicovolcanokoniosis...

Doesnt revenge rhyme with orange?

No......
