Quanti-FreshBrand of air freshener developed by Danish physicist Mikael Nedersen that worked by taking air pockets from alternate universes and injecting them into ours, giving us completely fresh air. Unfortunately, the same device was developed simultaneously in several parallel worlds by Michelle Nedersen, Mikael Dendersen, Mitchell Neederson’s third head, Earth president and sentient Num Lock key Mo’ Dandy, and the ghost of Richard Pryor, and soon air was being imported and exported throughout the multiverse with no regulation. A G-infinity summit was eventually held in which it was decided that air would be taken from a universe in which humans had evolved without lungs, pumped through all other universes (in order of stuffiness), and finally dumped in a universe devoid of fossil fuel and heavily reliant on wind energy. It is predicted that this last universe will eventually burst under the pressure, but experts point out that in an infinitely varied number of universes, at least one person will have figured out a solution. They are yet to identify themselves.
