Matt, don't worry about ammonia, ash, blah-blah-blah.

I don't even know why he's placing these worries in yer head.

Pipe smoking is easy... keep "it's easy" in yer head.

When I smoke my pipe and it goes out, I relight it. If I'm done with my pipe I stick it in my shirt pocket. When I want some more I pull it outta my pocket and relight it. Easy Peasy!
