"I feel lucky like a four leaf clover"?No cheating, guess what song are these lyrics out of?

No google!I had to google because i love then in the song and i misunderstood the line, ha ha!It sounded to me "funny flower or clover" which made nonsense.I finally got it!I think i'm not a cheater if i did that!I know and like the song a lot!^_^
