1. The astronomer in the office next to me just said "I don't want to know how my computer works. I just want someone to set it up for me."
2. The speaker at colloquium said "the energy released is 10% of what happens in other situations... so the stars are given a kick that's only 40 km/s instead of 400 km/s."
Number one just pisses me off. There are a lot of people like that here and, as a result, the solution has been to go for the least common denominator and set up the computers so that the end users can't change anything at all.
The problem with number two is left as an exercise for the reader. Points to the first person who posts a comment with the problem identified.
