This is what I was going to say.

I think we forget, (because cigars have gotten so much more expensive in the last 10 years) they aren't really meant to be smoked down until they burn your fingers, or re-lit multiple times.

Purging does work to a degree, but sometimes its just best to pitch it and light a new one. However, I admit this can be tough to do when you're smoking a $8 or $10 cigar.
