翻譯：我想說的是，說我在偌大一座城市可能碰到過他的朋友，真是可笑。　　

順便說一句，這個句子雖然在網上到處可查到，但它不是一個地道的句子，應在 that 后面加上 it 或將 that 改為 it。即：I felt like saying that it was funny to say I could possibly have ever met his friend in such a large city. / I felt like saying it was funny to say I could possibly have ever met his friend in such a large city. 　　

句子分析如下：saying 后面接的是以 that 引導的賓語從句（that 可以省略），it 為賓語從句的形式主語（真正的主語是其后的不定式 to say I could …）。
