You know that being hit over the head with an adjustable piano-stool [凳] can give you a nasty[令人討厭的] headache.
你們知道被一個高度可調的鋼琴凳打中腦袋會產生讓你討厭的頭疼。

A lot of people going into retirement find that the biggest challenge is adjusting to just sitting around doing nothing. With him this won’t be a problem. With our company alone, he’s had over thirty years of practice.
很多人退休后發現最大的挑戰是能調整自己坐下來什么也不做。對他來講，這不什么問題，單在我們公司他就已經練習了30多年。
注：在員工退休歡送會上調侃退休人員。
