Oh yeah, Sgt. Guffy!!!! He was great in that, in fact most of them were good! Even when I was in the army, 1958 to 1962, the bartering and finagling between the G.I.s was continuous 24/7. Most common was a pack of cigarettes today for two packs on payday! Everybody smoked back then!The horse trading GIs remind me of Telly Savalas' character in 'The Battle of the Bulge'.
