In an episode of Sponge Bob Square Pants, he gets the Suds, which is strange in a sponge which is already made of  3-D contiguously tightly packed heterogeneously assorted thin walled spheres, albeit more stable than suds but very like it.  Unlike Sponge Bob I like suds, its airy mallow, baroque exuberance and ephemerality are fine qualities for baths and here, where the humble act of washing a large vase produced a satisfying surfeit of suds, followed by an intriguing subsidence, as if one part of the suds is thinking of leaving but doesn't quite have the wherewithal.
