Beavis as Betsy Ross
Beavis and Butt-head do vexillology in thier next to final 'normal' episode - #199 - Our Founding Losers. Beavis and Butt-head came to us out of the creative imagination/confessional of Mike Judge back in 1992. Beavis and Butt-head ran for five years from 1992 until 1997. The show is epic of youth culture in the 1990s. It aired just before the dawn of text head-zombies and instant pestering, and captured the national psyche on a diverse set of demographics.
Beavis accidentally standing on the US Flag
In this episode Beavis and Butt-head were supposed to lower the US flag at their High School - Highland High. However their consistent ineptitude shines its inglorious lime light as they bungle the simple act of lowering a flag - which any high school grad should be able to do. The Star Spangled Banner unpatriotically hits the ground. Soon enough they find themselves bickering and Beavis unintentionally steps on the American Flag.
However Mr. Buzzcut is witness to this tragic event and punishes them with a writing assignment, which is to write an essay about the founding fathers of the United States of America.
Beavis and Butt-head try their best. Their effort is geniune yet paltry. It is proverbially well below the American Standard.
