One time a couple of World War II veterans, Dwayne and Lonnie, were attending a Reunion and Dwayne asked Lonnie.
"Do you remember that stuff they used to put in our coffee during the War, to make us forget about women?"
Lonnie replied "I think you mean salt peter."
Dwayne answered, "Yep, that's the stuff. Well, I think it's finally beginning to work!"
