'Allo 'Allo - Swedish Art Expert

Swedish art expert Yoop Hoop de Hoop, from Episode 21 'Flight to Geneva' of Series 5 of 'Allo 'Allo!, written by David Croft & Jeremy Lloyd.

Von Strohm fixes his telephone with a piece of chewing gum, so that he and Gruber can hear every word spoken in the office on Helga's telephone. This is so they will be able to find out on which train the paintings will be sent. The next moment, general Von Klinkerhoffen arrives with the Swedish art expert Yoop Hoop de Hoop and the colonel and the lieutenant are ordered out into the ante room. The general knows of the chewing gum trick and thus eliminates that way of listening in on him and the expert. The colonel therefore orders the lieutenant to go outside and climb up to the office window, to hear what is being said in the office. When the general and the expert have finished and let the colonel have his office back, he discovers that Gruber has not managed to climb the ivy, but instead, Helga has been hiding behind the curtain and heard what has been going on. The paintings have been authenticated, but they are not to be sent to Hitler. The art expert has instead paid the general one million in gold bars (in a suitcase) and will send the paintings to "his client" (who is unknown) in Geneva. - Wikipedia
