I always have a difficult time choosing original birthday presents. My imagination never seems to get beyond ties, handkerchiefs, or pairs of socks. But, strangely enough, it did not take me long to decide on Tom’s birthday present. For the first time in my life I had a good idea--I would buy him a bottle of champagne. Before the party began, Tom suggested that I should open the bottle. I put it between my knees and began to pull, but it remained firmly corked. Soon a crowd gathered round to watch the fight between me and the bottle. I could hear all sorts of" helpful" suggestions from the guests like "Break the top off", "Use your teeth!" etc. But I was losing the bottle. We were struggling on the floor together, when all of a sudden there was a loud "pop!" and the cork shot up into the air, while the angry bottle showered everybody with champagne!
