最近樂陶陶兄弟很愛這首歌。
Knock Three Times 每次播放，兄弟倆總是跟著唱，
Oh my darling
Knocks three times on the ceiling if you want me
” Twice on the pipe“ （註）if the answer is no
Oh my sweetness, knocks three times
Means you'll meet me in the hallway
Twice on the pipe
Means you ain't gonna show
註：
每次唱到twice on the pipe，兩兄弟就會故意唱「外送的派」，然後瘋狂大笑。
不過台灣好像沒什麼外送的派吧？外送的披薩比較多。
