"They Can't Take That Away from Me" was a George Gershwin song that Vic Fontaine sang. It was included in the hologram Vic Fontaine's repertoire. In 2374, after spending time in Vic's lounge, Odo had the song stuck in his head and began humming and singing the song without realizing it during a meeting with Sisko. After Sisko pointed out that Odo was singing, the two sang the song together as Sisko read Odo's report. (DS9: "His Way")
