In space no one can hear you ...

Here's one for the astronauts amongst us.

If you're in your space capsule, floating about in zero gravity and you fart, will you be propelled forward?
I mean, this could be quite problematic, couldn't it? A good curry the night before, and you could be bouncing around inside the capsule doing a rather splendid impression of a balloon that has just been let go.

Just wondering.
