Sven walks into a bar... ... and sees his friend Bjorn sitting alone at a table. He orders a vodka, and sits down opposite him. Bjorn looks up and nods. Sven nods back. They sit like this, not speaking, for hours, waving to the barman when more vodka is required. Eventually Sven says, ""Snow again."" Bjorn replies, ""Look, if you're going to chat all night, then I'm going to have to find another bar.""
