I've always wondered what spotted dick actually has in it so I looked it up on Wiki. It wasn't very informative, but this was interesting regarding the origin of the name:
"It is possibly conjugated originally from sticky pudding to dicky pudding to dicky to dick and finally spotted dick as in pudding with raisins. It is also known as spotted dog, plum duff, steamed dicky, figgy dowdy, dotted lloyd, packphour's lament, dicky widmark as well as plum bolster, Spotted Richard and, occasionally, Dickie Burton after the famous actor".
That's almost as funny as looking up rude words in a thesaurus.
