Shared Associations -- An Example from Married Life.

Friday, about 2:30pm. Hubby,in bed, still sleeping off the night shift. Wife,wanting to be close but not wake the hubby, enters with book and stretches out on the other side of the bed. Begins to read. Grows more and more amused. Chuckles sporadically.

Husband begins to stir. Wife chuckles again. Husband rolls over.
"What are you laughing at, Wife?"
"This book."
"What book is that?"
"'The Three Musketeers'"
"Who is that by?"
"Alexandre Dumas. It's full of, um, lots of sword-fighting and killing. I'm only into, like, the third chapter and I think five people have died already."
"Ohhhh." Husband chuckles and begins to sing. "'The first one he came to, he ran him through amain. And the second one he came to, he served him just the same...'"
Wife chuckles. "Exactly like that, though the others don't flee."

Thus the association is fast made between "The Three Musketeers" and the "Jolly Soldier".
