Me, and I'm sure, many others as well.
I remember thinking it a treat warming up 1944 dated C-Rats on the manifolds of my boat in 1969. And being 25 years old they tasted pretty darn good. Must have had great preservatives back then. I didn't smoke and traded the little five pack of cigarettes for the Chiclets. Eventually they ran out and is was catch as catch can. I hated those long insertions.
