Retweet: Shaq vs. Danica?

Could "The Diesel" be the heading to IndyCar Series racing? NBA star Shaquille O'Neal, who has used "The Diesel" among his many nicknames, sent the following message to IndyCar Series driver Danica Patrick via social networking site Twitter recently:

O'Neal: "vroom vrooom I challenge u to a race, vroom$ vroom, naaa good luk, u r a true legend, I'm proud of u u r da best"

Patrick, the first female to win an IndyCar Series race responded: "I will race you! I think I have a slight weight/height advantage so I feel confident! Haha."

The race isn't the only connection to the IndyCar Series for O'Neal, who also issued a challenge to race Lance Armstrong (a former Indianapolis 500 Pace Car driver) via Twitter.

O'Neal recently joined forces with Luczo Dragon Racing to raise money and awareness for charity throughout the 2009 race season and will be a guest of the team at Texas Motor Speedway in June.
