There must be a name for that peculiar, painful, restrained explosion of laughter when you're at work and don't want to be caught mudcatting--you know..but the laugh caught you off guard...

...or even the embarrasing tears when the mudcat has taken you on some beautiful journey...but unfortunately, those around you weren't on the trip. "uh...yeah..I'm crying...uh..this is really great new software, huh?"
