It would be much more fun if the TDCs would actually respond to any sort of fun. But as is par for a TSA employee, they are just sheepwalking. On three separate occasions (1 @ IAH, 2 @ SFO) I've been asked, "Can you state your first* and last name?" (*at IAH only). I've simply responded, "yes". All three times, they have just handed me my BP and ID.
