On the back of a TARC bus:
Son in jail? Call Waddell!
along with the phone number of the honorable Mr. Waddell, attorney at law, all transposed over a huge photo of Mr. Wadell's grinning mug.
Of course, just north of Louisville, this is a more straight rhyme - as when "jail" rhymes with "gel". Or further south, when "jail" becomes a two syllable word ("jay-uhl", long "a" sound) and Waddell becomes a three syllable word ("Wha-dahy-uhl", short "a" then long "a").
Stay classy, Louisville.
