@Alice@beige.party My brother could never pronounce “chipotle” correctly; he always reversed the L and T. Probably because the T-L combination doesn’t occur in English that often.

@karlauerbach This is some Kim Jong Eun level cult of personality shit. (In fact, North Korea doesn’t have Kim’s picture on the passports, which says a lot about how bad this is.)

Wouldn’t it be great if King Charles came to the podium in Congress and said only four words: “We are not amused.”

Replying to @artemis@dice.camp
@artemis For those who might be considering teaching: for community colleges (at least in California) you only need a Master’s degree in the academic area you teach. The money isn’t great, but many community colleges will hire part time adjunct faculty. Also, if you are teaching a course that is articulated with a university system, then it is at the same level as university. It’s not watered down. For example, the data science course at the college where I taught uses the same materials as the beginning data science course at UC Berkeley.

Perhaps we should rename the Strait of Hormuz to “Schrödinger’s Strait’. It is open and closed at the same time, and its true status can only be known when it is observed by a government.

Given that it’s a waterway, I would add a joke about the wave function collapsing, but nothing comes to mind.

@ShaulaEvans I would never criticize Chris Christie for his size. He knows it’s a problem, and he’s working on it. (Jokes about bridges, on the other hand...) When Donald Trump or his supporters portray him as a magnificent physical specimen, I think mocking them is not out of bounds.

At left, a large orange circle with the words Trust, Partnership, Innovation, Performance (one word per line) At right, a small yellow circle with the words OUR VALUES. There is a very small overlap between the circles, making it appear to be a Venn diagram with very little overlap between the words at left and the values at right.

There is a burning pile of wood in the middle of the boat. The Captain appears to be warming his hands. Tintin and Milou are aghast (word balloon: “!?”)

@digichelle@hachyderm.io Agree; it should not be asked. If someone does ask me, I’ll jokingly say “I’m mean enough when I’m sober.” (The real reason is that I don’t like the taste of alochol - for me, it tastes bitter, but telling people that does not dissuade them: “Oh, you’ll like .”)
