1) A saying said by Bart Simpson in seasons 1-9 of the popular animated comedy The Simpsons, until someone got themselves fired and everything got screwed up.

An admonition spoken to a maleseahorse who is concerned that he's gonna give birth to sea CATTLE instead of sea HORSES.
Most creatures reproduce though the female, with the male providing fertilization of her eggs while their still "in her oven". But male seahorses do somewhat the opposite --- the female deposits her sterile eggs into the male's sperm-filled egg-pouch, where the eggs are fertilized and remain till they hatch. Once in a while, though, something goes wrong with the process, and the male becomes concerned that his eggs are turning into aquatic cattle instead of horses, prompting others in his clan to anxiously admonish, "Don’t have a cow, man!"
Utility beer is the beer you keep around for the day-to-day moments when beer is a necessity to assist in pedestrian activities (golf, plumbing, yardwork, babysitting, staff meetings, Zoom calls). For the beer snob it is the beer you save for neighbors when they drop in at 3 p.m. on a Tuesday. It is differentiated from the actual high-end beer you save for special events, holidays, and special tastings.
Person 1: Dave, did you bring along those hazy craft IPA's so we could drink while cleaning Lyle's pool?
Person 2: Nope. I just have a bunch of utility beer that Steve dumped on me. Good enough for this. It is only 10:30 a.m.
