'Orange' is an unrhymable word. Of course, you can get around this by utilizing some poetic license. Willard Espy's “The Unrhymable Word: Orange” jams with enjambment by informing us that: "The four eng-/ineers/Wore orange/brassieres."
I don't own an orange brassiere, but I am fortunate to own both a rhyming dictionary and some fine John Masters Organics products.
Admittedly, I go for orange because I like the scent.
