Here's what's found:

General notes: Jordan's round fluid stroke in his writing indicates fluidity of thought and movement.

  The loop at the bottom of the "M" is a "worry loop." It shows he spends time worrying about things that often never happen.

  The downhill slant of the "M" indicates diplomacy.

  The aggressive hooks on the bottom of the "M" and "J" -- plus the long downstrokes -- indicate determination and physical endurance.

  The straight baseline indicates perfectionism. He wants structure and follows habits. He is very intolerant of sloppiness.

Here's what's found:

General notes: Rodriguez uses large capital letters -- very similar to the signature of Michael Jordan. His signature indicates that he is ethical, emotionally normal and very motivated by approval.

  The large capital "A" and "R" indicate a person with a healthy ego, but not necessarily an arrogant one.

  The clean "o" reveals a person who is blunt, honest and candid.

  The large loop in the stem of the "d" indicates that Rodriguez is extremely sensitive to criticism. Approval definitely is highest motivation.

  The figure-8 shape of the "g" indicates fluidity of thought and movement. This is very typical of finesse athletes, writers and people who are good speakers.

  The closed "e" shows a person who doesn't listen well and is a bit close-minded.

  The large loop in the "z" indicates a person with a large imagination -- a good storyteller.

  The elegant fluidity of movement at the base of the "g" is typical of smooth talkers, great dancers and good writers.

Here's what's found:

General notes: DiMaggio's signature slants to the right, which indicates that he is implusive, passionate and tends to be subject to manic highs and lows. When he was "on," he was a huge asset. But when he wasn't, he was probably prone to depression.

  The high ending stroke on the "e" indicates a desire for attention.

  Similar to the signature of Michael Jordan, DiMaggio has a "worry loop" in his "M." This shows that he often worried about things that never happened.

  The convoluted "a" reveals a fear of telling the whole truth. It's a sign of a person who's exceedingly diplomatic and willing to save face.

  The long downstroke on the "y" indicates determination and physical endurance. This is one of the most common threads among the signatures of athletes. You wouldn't see that downstroke from a lot of stay-at-home moms.

So, what does Simpson's signature say about his personality? We analyzed Simpson's autograph and tell us what it reveals about the NFL Hall of Famer.

Here's what's found:

General notes: I would guess that this is an autograph from Simpson before the double-murder trial. This signature is not angry or tempermental. The round shapes indicate a person who is kind. This certainly doesn't indicate a person who is prone to violence, aggression or lying. This is not the handwriting of a killer.

  The big loop in the "O" reveals a person who is very secretive and evasive.

  The "i" shows a person who is direct and gets to the point.

  The circle dot for the "i" indicates a desire to be noticed.

  The shaky humps in the "m" and "n" are not formed with precision. This usually indicates a low level of education and a person who doesn't have a high level of mental processing.

  The extended length of the bottom of the "K" shows good determination.

  The point in the "n" indicates a fast thinker with a brilliant, lightning-fast mind. He's also very impulsive. The size of the "g" shows he has a large imagination and is a good storyteller.

  The triangle at the base of the "g" indicates anger related to his sexual desire and religious upbringing. He is a bit curious and experimental.

  The "t" brace is a sign of stubbornness.

Here's what's found:

General notes: This signature reveals a person who is impulsive and emotionally driven. In case you're wondering -- and I'm sure you are -- you can't tell about Kournikova's sex drive because there is no "y" or "g" in her name. The upward slant in her name indicates an optimistic attitude. This is the handwriting of a person who always looks on the bright side of life.
