Fact is, we've all missed out on dream cels, 
sometimes by as little as a minute or two.  It's 
enough to make you want to whack your head into 
the desk a few times and then go out for a really 
huge drink.

But remember that (with a very few exceptions) 
there are more cels out there of any given 
character or scene, and you might be the lucky one 
next time.
