水上漂（唱）

老汉心并非铁石块，

是留是丢几徘徊……

狗娃 （抓住一线希望，急唱快板）

我比男娃子更勤快，

能干粗活能挑抬。

下河帮你洗铺盖，

煮饭帮你劈干柴……

你桌上只添一双筷，

我不贪嘴，不挑菜，

学本事，听安排……

爷爷呀——

你收个孝顺的孙女划得来！

水上漂（唱）

可怜可爱，

好灵好乖，

催人滚滚泪！

背着狗娃揩……（返身望天三思）

雁鹅阵阵飞天外，

炊烟袅袅起楼台。

我家香烟今何在？

愧对祠堂祖先牌。

养儿方能续后代

女生外向招祸灾。

事出无奈，

快快丢开。

狗娃休把老汉怪——

重男轻女自古来！

    水上漂心一横，跺脚踢开女孩，跳上小舟，轻篙一撑，船如箭发，开往下游。

    狗娃沿着河岸追赶小舟，踏进浅水呼唤爷爷，水漫到膝，波涌到腰……

    水上漂回头一看，女孩在水中沉浮！

水上漂  死丫头，不要命了！

    老汉嘴上大骂，行动却很果断——投河救人！

    艺人不愧外号水上漂，弄潮之术极高，迅速救起女孩。
