I phone the first tricorder

Have you seen the commercial for the I phone. "Theres a knack for that?"

"Want to know if that is poison ivy your standing in, theres a knack for that."

"Want to know how many calories are in that sandwich you are eating, theres a knack for that."

"Want to know how much money you spent today, theres a knack for that."

"Want to know what I think, Because theres a knack for that too!"

"I phone the first tricorder!"

Just something silly that I thought of!
