Astronaut Humor: When does it go too far?

We all know that feeling of telling a joke you know is not going to be funny, while you're saying it, but you power through it like a champion and cover up the ensuing awkward silence with boisterously loud self-laughter as you see the faces of those around you turn into something more dense and embarrassed for you than a granite statue of your mother. It's not fun, but that's sometimes the way it has to be.
