Carrying on with the show without Charlie would be nearly impossible; not to mention changing the title of the show to One and a Half Men or Two Men and Surly Housekeeper wouldn't be as hilarious.
I'm not the only one that feels bad about the cast and crew who are now unemployed because of one jack ass.
I'll be surprised if the show came back for another season. If they did, maybe they could write Charlie off...
But really - meh. Never got terribly attached to the show.
