Fellas, with the introduction of the Meadowlands Farm giving you two baby chicks to start out with as well as the 1.6 Update introducing Mayo as a dink. I believe we all know what the next non-serious (like the hat-on-sea-urchin run) speed run is.

Mayo %, must obtain an egg and a Mayo maker by any vanilla means necessary (So, eggs from the traveling cart would be a-okay). Then you must make a jar of Mayo and then proceed to drink it as fast as possible in order to complete the run.

Standard rules of starting from a fresh meadows farm save of course.

I'm not good with tech, but if someone does not do a Mayo% run within a week, then I will probably figure out how screen recording and overlaying a timer in Stardew valley works and attempt the run myself.
