You'd laugh to see a pudding crawl is a catch-phrase aimed at someone who is easily amused or is suffering a fit of uncontrollable hilarity. Does anyone know how this phrase came into being?
I'm not even sure what is meant by a pudding crawl; I presume it means the act of the last part of your meal propelling itself about the table, but perhaps there is another meaning that would make the saying clearer?
Searching the internet revealed that the question has been asked before (here), and the meaning explained (here and here) but the etymology has never been explained.

Matt's idea that the phrase might have a different meaning in each saying seems probable to me.
I've been slightly more successful searching for see a pudding crawl on its own (without the laughing part). And it is a lot more frequent with creep than crawl.
There's a peak in the early 19th century for see a pudding creep because it was used in an essay by Jonathan Swift :
where it could be understood as "see a pudding go to waste".
The oldest quote I have found is in a 1617 nonsense anonymous verse :
Here again it's the idea of waste. So how did it become associated with laughter? (A hint of sadism maybe?)
The phrase seems to be British (rather than US), here's an excerpt to what seems to me to be a pastiche from the TV series Star Treck:
It can found in a cockney dictionary and a 2005 excerpt from a web blog:
