美國流行笑話：How long? 要多久？

172　How long? 要多久？

Knitting is a passion for my friend Lisa, who is a caregiver for the elderly. When she brings her clients to doctor's appointments, she knits while she waits. Recently she showed me a gorgeous scarf she'd made. “How long does something like that take?” I asked. “About one stress test and one colonoscopy,” she estimated.
編織是我朋友麗莎的喜好。她是專職照顧老年人的。當她帶老年人去看醫(yī)生的時候，她就邊織邊等。最近，她給我看她織的一條非常漂亮的圍巾。我問她：“像這樣的圍巾要織多久？”她估計說：“大約一次心臟強度測試加一次結腸鏡檢查。”
