The Jerk in the Box

I am constantly thinking of products that might help fellow commuters cope with the discomfort of ambient cell phone chatter. My newest invention is a Jerk in the Box. Basically, it's a Jack in the Box. Same metal box. Same music driven by a cranking mechanism. The difference is that the harlequin who pops up is holding a tiny cell phone to his head. It's all in the application—next time you are plagued with a chatterbox on the train, you simply whip out the old "Jerk" and crank away. Everyone will have a huge laugh at the caller's expense.

Another idea was to create a telescoping wand with a tiny cell phone on the end. When someone goes overboard on the phone, you walk over and clock him or her on the head with the fully-extended wand. Again, this relies on a bit of public humiliation.

Then, of course, there's the cell phone jammer. They're illegal here in the US, but I understand people buy them overseas and point them furtively at unsuspecting talkers. Brilliant and far more effective than my ideas. But where's the public humiliation?
