Just answer a completely different question. Example
TSA Idiot: "Could you verify your last name"?
TSA Victim: "Cincinnati, then back home"
TSA Idiot: "No, I need your name"
TSA Victim: "No, I'm not famous, I'm just an engineer"
TSA idiot: "I NEED your NAME!"
TSA Victim:"I'm sorry I'm hard of hearing, could you repeat the question?"
TSA idiot: "YOUR NAME YOUR NAME"
TSA Victim:"Oh its right there on the boarding pass, its ok we all have disabilities, mine i S. M. I. T. H. That spells "smith...."smeeetheeee". Them giving him a condescending nod and smile
In all seriousness, I have found that frustrating the TSA sex perverts, making them work extra hard, but all done with plausible deniability gives me something to laugh about after I leave the TSA grope point, and helps relieve the incredible tension these low lifes tend to induce.
