I mean, organic fibers like cotton can and will degrade over time. Especially if there is other organic activity going on in the environment. Yeah completely unadorned skelis would be a bit odd. Honestly in this setting I would actually expect the skelis to
Have more complete clothing as it looks like they’re in a fairly sterile and artificial environment and I’d imagine their ‘space clothes’ are synthetic.
Also, a lot of the time it doesn’t mean there isn’t a real studio audience actually laughing at the performance. It’s just much easier to layer in canned laughter than record the actual live audience. This isn’t the case for stuff like SNL but a lot of live to tape stuff will use canned or prerecorded audience noise on top of a real audience.
Regular soap does also kill bacteria with those hydrophobic sides of its molecules by breaking a bacteria or virus’ lipid membrane. I would argue this still a mechanical process though. Antibacterial soaps use a specific chemical, Triclosan, that binds with enzymes within the bacteria that prevent it from reproducing.
Outside of antibacterial or germicidal soaps, the cleaning action of washing with soap is 100% mechanical. Soap molecules are asymmetrical and have one side that’s hydrophilic and one side that’s hydrophobic which, when used with water, creates a nifty mechanism that picks up crap on one side and catches a ride on the water molecules with the other side.
well ow d’ya know he’s a king then?
