请用150个左右的单词把《画蛇添足》的寓言故事写出来，以便刊登在某英文刊物上“成语介绍”专栏上。故事大意： 　　从前，有三个人得到一壶酒。他们决定在地上画蛇，先画好的人就喝这壶酒。有一个先画好了，拿酒准备喝，见另两人还未画完，就说：“我还能给蛇添上脚呢！”但脚未画完，另一人已把蛇画好了，说：“蛇本来没有脚，你怎能给它添脚呢？酒该我喝了！”。 　　范文: 　　Onedaythreemengotabottleofwine.Butthewinewasnotenoughforthemthreeandeachofthemwantedtodrinkthewinealone.Thentheyallagreedthattheyeachwoulddrawasnakeonthegroundandtheonewhofirstfinisheddrawingwouldbegiventhewine.Sotheybegantodrawonthegroundwithsticks. 　　Itwasnotlongbeforeoneofthethreefinisheddrawinghissnake.Hefoundtheothertwowerestillbusywiththeirdrawings.“Howslowyouare！”saidhe，“Icanevenaddfeettomysnakebeforeyoufinishyours.” 　　Heputdownthebottleandbegantoaddfeettohissnake.Butbeforehefinished，anothermantookholdofthebottleandsaid，“I’vefinished.Snakeshavenofeet，soyoursisnotasnake.”Withthesewordshedrankupthewine.
