有點像 Charles Penrose 的《The Laughing Policeman》，裏面笑聲很多，下面是歌詞，妳搜來聽壹下看看是不是這首
歌曲：The Laughing Policeman
演唱：Charles Penrose
I know a fat old policeman he's always on our street
A fat and jolly red faced man he really is a treat
He's to kind for a policeman he's never known to frown
And everybody says he's the happyist man in town
Ha Ha?Ha Ha?Ha Ha?Ha Ha Ha Ha Ha Ha Ha Ha...
The laughs apon duty he laughs apon his beat
He laughs at everybody when hes walking in the street
He never can stop laughing he says he has not tried
And once he did arrest a man and laughed untill he cried
Ha Ha?Ha Ha?Ha Ha?Ha Ha?Ha Ha?Ha Ha Ha Ha...
His jolly face is wrinkeled and then he shut his eyes
He opened his great mouth is was a wanderus site
He said i must arrest you he dint know what for
And then he started laughing until he cracked his jaw
Ha Ha?Ha Ha?Ha Ha?Ha Ha?Ha Ha?Ha Ha Ha Ha...
So if you chance to meet him when walking round the town
Just shake him by his fat old hand and give him half a crown
His eyes will beam and sparkel he will gurgle with delight
And then you will start him laughing with all his blessed might
Ha Ha?Ha Ha?Ha Ha?Ha Ha?Ha Ha?Ha Ha Ha Ha...
PS：還有個中文翻唱版，是洪鐘的《奇妙的約會》，裏面笑聲也是很多的，希望能夠幫到題主妳
