My favourite spot - Stiegl beer advertising

My favourite advertising is the spot from Stiegl beer, because it's very funny.
The spot takes place at a party. A man shows a stairs-sign to a woman, because he wants to drink a Stiegl beer with her, but the woman thinks he wants to go upstairs with her and goes away. A few moments later another woman shows a stairs-sign to the man, who thinks she wants to drink a Stiegl beer, but the woman has got a Stiegl beer and wanted to go upstairs. So the man is lucky and they go upstairs together.
