戰(zhàn)國(guó)時(shí)候，齊國(guó)的孟嘗君喜歡招納各種人做門(mén)客，號(hào)稱(chēng)賓客三千。他對(duì)賓客是來(lái)者不拒，有才能的讓他們各盡其能，沒(méi)有才能的也提供食宿。
　　有一次，孟嘗君率領(lǐng)眾賓客出使秦國(guó)。秦昭王將他留下，想讓他當(dāng)相國(guó)。孟嘗君不敢得罪秦昭王，只好留下來(lái)。不久，大臣們勸秦王說(shuō)：“留下孟嘗君對(duì)秦國(guó)是不利的，他出身王族，在齊國(guó)有封地，有家人，怎么會(huì)真心為秦國(guó)辦事呢？”秦昭王覺(jué)得有理，便改變了主意，把孟嘗君和他的手下人軟禁起來(lái)，只等找個(gè)借口殺掉。
　　泰昭王有個(gè)最受寵愛(ài)的妃子，只要妃子說(shuō)一，昭王絕不說(shuō)二。孟嘗君派人去求她救助。妃子答應(yīng)了，條件是拿齊國(guó)那一件天下無(wú)雙的狐白裘（用白色狐腋的皮毛做成的皮衣）做報(bào)酬。這可叫孟嘗君作難了，因?yàn)閯偟角貒?guó)，他便把這件狐白裘獻(xiàn)給了秦昭王。就在這時(shí)候，有一個(gè)門(mén)說(shuō)：“我能把狐白裘找來(lái)！”說(shuō)完就走了。
　　原來(lái)這個(gè)門(mén)客最善于鉆狗洞偷東西。他先摸清情況，知道昭王特別喜愛(ài)那件狐裘，一時(shí)舍不得穿，放在宮中的精品貯藏室里。他便借著月光，逃過(guò)巡邏人的眼睛，輕易地鉆進(jìn)貯藏室把狐裘偷出來(lái)。妃子見(jiàn)到狐白裘高興極了，想方設(shè)法說(shuō)服秦昭王放棄了殺孟嘗君的念頭，并準(zhǔn)備過(guò)兩天為他餞行，送他回齊國(guó)。
　　孟嘗君可不敢再等過(guò)兩天，立即率領(lǐng)手下人連夜偷偷騎馬向東快奔。到了函谷關(guān)（在現(xiàn)在河南省靈寶縣，當(dāng)時(shí)是秦國(guó)的東大門(mén)）正是半夜。按秦國(guó)法規(guī)，函谷關(guān)每天雞叫才開(kāi)門(mén)，半夜時(shí)候，雞可怎么能叫呢？大家正犯愁時(shí)，只聽(tīng)見(jiàn)幾聲“喔，喔，喔”的雄雞啼鳴，接著，城關(guān)外的雄雞都打鳴了。原來(lái)，孟嘗君的另一個(gè)門(mén)客會(huì)學(xué)雞叫，而雞是只要聽(tīng)到第一聲啼叫就立刻會(huì)跟著叫起來(lái)的。怎么還沒(méi)睡蹭實(shí)雞就叫了呢？守關(guān)的士兵雖然覺(jué)得奇怪，但也只得起來(lái)打開(kāi)關(guān)門(mén)，放他們出去。
　　天亮了，秦昭王得知孟嘗君一行已經(jīng)逃走，立刻派出人馬追趕。追到函谷關(guān)，人家已經(jīng)出關(guān)多時(shí)了。
　　孟嘗君靠著雞鳴狗盜之士逃回了齊國(guó)。
