Art, for F@rTs Sake !!!

 These are the distances computed between each of your words:

	rectum	fart	anus	sphincter	bum	asshole	gas
rectum	-	67	17	33	63	54	80
fart	67	-	59	76	49	50	72
anus	17	59	-	34	51	36	84
sphincter	33	76	34	-	75	59	88
bum	63	49	51	75	-	43	87
asshole	54	50	36	59	43	-	87
gas	80	72	84	88	87	87	-

You can try completing the task again now that you know how it is scored, but note that only your first score counts as a valid measure of creativity.
