I'm not sure if such a thing is even possible (and no, I'm not going to google it and find out. I don't want to give google ideas for ads to send my way).
However, I can only imagine that finding a willing donor might be a problem.
Anyway ...
Lamb - The sheep heard about the abattoir, so they're on this ... which is why we're having chicken tonight.
Orange - What we'll surely avoid scurvy if we all eat. Also rhymes with 'door-hinge'.
Purple - A word that some claim has no rhyme, but I disagree, because of the existence of the words 'hirple' (a Scots word meaning to walk with a limp) and 'curple' (a horse's backside). So now we know.
