Stuff stolen from your car

The other day after a cruise I got into my car and noticed that the selector window on my B&M shifter was gone. Sometime jurning the show someone reached into,or got into the car and popped it off...you gotta be kidding me..if your going to risk getting caught steeling you think it would be for something worth while.
First time anyone has burned me at a show.
What have you had ripped off that made you shake your head?

When i had an older jeep for a daily driver.(no locks), i went all summer with a bikini top and no one though twice about messing with it. The first week i put on the soft top. Someone got in it and stole my radio faceplate and all the CD's in the jeep(all copied CD-R's)
