Who says astrophysicists don't have a sense of humor? This probably freed up a few tenured positions:

For exploring the physics behind the accelerating universe a crucial question is how much we can learn about the dynamics through next generation cosmological experiments. For example, in defining the dark energy behavior through an effective equation of state, how many parameters can we realistically expect to tightly constrain? Through both general and specific examples (including new parametrizations and principal component analysis) we argue that the answer is 42 - no, wait, two.

In the olden days of actual slides, the best they could do was stick a slide at the end. It took too long to shuffle all the rest of the slides to get away with it undetected. (So, yeah, somehow despite all our best attempts to guard our slide carousel prior to our talks, somehow someone always managed to slip some mildly embarrassing photo ahead of the acknowledgments slide at the end. No, you can't even trust your own mentor to guard your slides. )
