Finally ... Friday afternoon is upon us. Just a couple more hours until quitting time. Here are a couple of websites to help you get there. This week's theme is automobiles.

Cash Cab: One of the installments from Discovery Channel, Cash Cab is a trivia game. Based on the television show, you pick your starting point and end point in New York, ride around in a taxi and answer questions for cash. You must arrive at your destination before three wrong answers to win the game. The faster you answer, the more money you get. Typos work against you in many cases, so accuracy is key. Also, don't forget your life lines, a street shout out and call a friend. I enjoy trivia and I consider myself a fairly good purveyor of useless knowledge. But that hasn't helped me here. This is a true time killer for me, because I have yet to win. So that keeps me coming back for more.

TypeRacer: You are up against seven other typists. Words appear on your screen and you type them accurately, spaces and punctuation included, to move your Volkswagon Beetle across the screen. It kind of looks like those carnival games where shoot water into a clown's mouth to race plastic horses. The words move across the screen as you type, which can be hard to get used to. But the best part about this time killer is that, if anyone is listening, you sound really busy.
