Never Have Your Dog Stuffed: and Other Things I’ve Learned by Alan Alda (2005)
Entertaining, revealing, but not about his career on MASH. This is a poignant story of an eccentric life with his Dad, a vaudeville performer, and his Mom who struggles with mental issues. Alda’s story is funny, conversational, and a great read. And, yes, they really did stuff his dog!
