ah yes

...I was reminded of this hilarious comic panel, after watching an episode of GOTHAM that had a scene of a mafia boss doing the same thing.

..." a disguised Liza visits Falcone in the park where she shares her opera music with him."

 ..ah, Hello, I was feeding these little birdies, but then I heard you humming a song my Mama used to sing to me..
Please come home with me and spank me, I have been very bad.

 Ok, the TV episode didn't say that exactly, but it fits,  right?
