HB, is a German cigarette brand whose initials stand for 'Haus Bergmann'. In the sixties and early seventies this firm produced several TV-spots with a comic figure, that is known in Germany as "HB-Männchen".
With simplest tasks the character started it always ended in disaster. A voice said: "Wer wird denn gleich in die Luft gehen, greife lieber zu HB" (means something as: Why freak out, have an HB-cigarette instead). While doing this everything turned out fine. Guillermo Perez
