Have you tried Navy rum? It's absolutely awful. Thousands of really good rums to choose from, and somehow the traditional one is the absolutely worst paint stripping bottom of the barrel rotgut they could find. I think it's intentionally bad so people don't even want the tot, let alone get drunk on it.
If it wasn't for the nostalgia I don't even know if they would sell it as an ultra low price mickey to homeless alcoholics.
