This is a riddle I first saw when I was in the 6th grade (like about 15 years ago). It's not well known and almost everyone I ask (even the really smart ones) never get it. So if you can get it I'll be very impressed.

In the above picture 3 tens are drawn. Believe it or not, there is a way to make these 3 tens mean the time 9:50 by drawing exactly one straight line somewhere on the paper. Can you figure out and tell me where and how to draw this line?

Update: Glenn got it so unless you want to see the solution don't read his posts!

If anyone knows any other good riddles I'm up for a challenge so feel free to post them.
