When I was eating spicy pizza at a restaurant I often visit, the chef had just made a batch of what he called "洋梨ワイン" ("pear wine"). My name ("Jonas") sounds like "pear" ("younashi") to Japanese people, so when he noticed that all the finished alcohol would not fit into the PET-bottles he had prepared he said that I should drink the stuff that did not fit. So I got some free home made pear liqueur. There was actually quite a lot that did not fit, so he joined me and we had about two classes each.
