The only problem with the ellipse, though, is that it usually has the 
connotation of a slow trailing off, rather than a sudden stopping.  (And 
btw, it's 3 dots if it's in the middle of a sentence and 4 at the end of 
a sentence.)
 Maybe a hyphen--

     Oh, quit ruining all my good ideas! :)
     Actually, I knew about the three dot elipse being the middle of a
sentence and that is why I thought of that idea. But, don't people use a
three dot elipse when they're indicating that someone's been interrupted?

     How about just a period?
     On second thought, maybe not.

BTW, in a monospaced font, this is a hyphen: '-' and this: '--' is a dash.
Little differences and all. But, back to the problem. How to cut off those
sentences...
