〔R20〕  Though I both foul

                 And dirty am,

                 And black as pitch can be,

                 There's many a lady

                 That will come

                 And by the hand take me.

〔譯註〕 雖然我既污穢

                  又很骯髒，

                  而且可能黑得像瀝青，

                  卻有許多個女士

                  她們會過來

                  抓著手帶我走。

〔提問〕 If I rhyme with “metal” (金屬) and I am a metal container (容器) for boiling or cooking, but I am not called a “pot,” what am I then?
