If you're looking to avoid the inevitable "Are we there yet?" question in your car, invest in a Pro Thumb Wrestling Arena ($7). Contoured thumb holes allow two digits to go head-to-head, or rather finger-to-finger, during road trips. Whether your kids are passing time on the freeway or airport runway, this doodad provides them with an organized activity that sure beats the seat-belt wars. And in case one thumb gets out of control, there are flexible ropes to keep the competition within the ring.
