I distinctly remember cafeteria from elementary school on. Our teacher in the 4th grade (around 1960) enforced every kid taking at least one bite of everything on their plate. When they served spinach, some of the kids, when the teacher wasn’t looking, would take their fork and make a depression the top of the spinach to make it look like they had taken a bite. As for me, I loved spinach and would clean up because the kids around me would happily share. Usually got an extra carton of milk also.
Poker was not invented until the late 18th century and became popular around 1800 along the Mississippi. The “flush” was introduced into the game even later. They may have said that, but probably not as a poker reference.
So, you are saying we should act like conservatives do when they lose; insult everybody’s intelligence with an absurd voter fraud hoax, then smash our way into the capital building to overthrow the election and threaten the lives of anybody that opposes our authority?
