Don’t be like this poor chap who learned that singing along to the Clash’s ”London Calling” (”Now war is declared/And battle come down”) in your taxi on the way to the airport can get you arrested as a terror suspect. To avoid trouble in these touchy times, stay away from Iggy Pop’s ”Search and Destroy” (”I’m the runaway son of the nuclear A-bomb… Baby detonate for me”), Fear’s ”Let’s Have a War,” Public Enemy’s ”Welcome to the Terrordome,” and of course, the Gap Band’s ”You Dropped a Bomb on Me.” Also, just to be really safe, don’t sing Patsy Cline’s ”Crazy.” (You can sing all the Toby Keith or Clint Black you want, though.) Finally, you’ll be arrested if you sing along to Black Eyed Peas’ ”My Humps.” Not for security reasons, just for bad taste.

Any other suggestions for the No-Fly-and-Sing list?
