> When you spend most of your waking hours working, that severely curtails your ability to make penis jokes (or really, any sort of joke). Meh, you could still do so within a group of friends even at a conference I would think, as long as it's in between sessions or otherwise at a break in the action. But when you're sitting in an audience surrounded by strangers and attending to whatever professional topic brought you there, it's probably not as good of an idea. I come from a community that is rather famous for being "not very formal", but we have a very clear distinction between when it's appropriate to be jovial and when formality is called for, and when formality is called for we go way above and beyond. Not because of sexism, but the neutrality of tone is definitely a nice side effect.
