Mr. Smiley does not sleep naked. The thought is too horrifying to contemplate.
Smileys, as a rule, prefer to remain clothed at all times, even in private. They simply do not want to risk the possibility that prying eyes might, well...you know. As a result, Smileys are expert at changing from one garment to another, without ever being sans clothing, even for a moment.
Mr. Smiley can remember how, when he was a boy, he heard his father speak in hushed whispers about what happened to Theobald Smiley, proprietor of a Cheese Shoppe. One day, in the store, Theobald's suspenders broke and his pants fell down. He was wearing underwear, but the sight was too shocking to bear; several shoppers fainted and were taken away by ambulance. Theobald sold his store and moved to the edge of Smileyville, where he lived out his days as a recluse.
As you can imagine, bathrooms are slightly problematic for Smileys. To begin with, bathrooms are always in the center of the house; there are no windows. There are no showers with glass doors in Smileyville. Bathtubs are surrounded by a "modesty screen".
If you visit Smileyville, the first thing you should remember is that bathrooms are private, as in one bathroom, one Smiley. In Mr. Smiley's oddly-shaped-and-brightly-colored house, there are four bathrooms: one is exclusively for Mr. Smiley; one is exclusively for Clothilde; one will be exclusively for Alexander, when he's old enough; and one is for guests.
If you actually use the guest bathroom, it will be completely stripped upon your departure. Towels and washcloths will be burned. Walls will be stripped and repainted, fixtures and plumbing replaced.
For plumbers in Smileyville, business is brisk.
There are no public restrooms in Smileyville. To a Smiley, the thought of using a bathroom that anyone else ever used is disgusting. Smileys who are out and about in town who feel an urge to...you know...are advised to either (a) hold it, or (b) go home.
Mr. Smiley's pajamas are blue.
