You could even do it like this;
In exasperation, Atanos replies bluntly to Dunor's question, saying, "We've found nothing."
by using the insert hyperlink button it will allow you to paste the link into the first bracketed section;
[ url=http://www.youtube.com/watch?v=r4-rYlw1rRI]
then in between close bracket and open bracket put in the color change and what will be said to ultimately look like this;
[ url=http://www.youtube.com/watch?v=r4-rYlw1rRI][ color=green ]"We've found nothing."[ /color ][ / url]
granted I have insert some spaces in the above so that the code wouldn't actually perform it and I could display what you would see in typing it.
This would serve two purposes, it provides the exact visual aide of how your character would be saying something, and also gives us the same comedic value.
Then any further discussion or comments on it, like Sk4mpE's +1 for spaceballs reference, would be appropriately put here.
btw another +1 for the spaceballs reference!
