As the NFL’s Pittsburgh Steelers continue to distance themselves from comments made by star running back Rashard Mendenhall, we thought we’d take a stroll down Memory Lane and point out some of our favorite athlete Twitter gaffes of the past few years:

1. Chris Cooley. In 2008, the Washington Redskins tight end thought it would be interesting for fans to see what his playbook looked like. So, he took a picture of it. While he was naked. Not only did the fans get a taste of what an NFL playbook looks like, they also got an idea of what’s inside Cooley’s jock strap. He quickly apologized for having the photo on his blog.

2. Chad Ochocinco. The Bengals wide receiver is, perhaps, the most visible athlete on Twitter, using it as a personal venue for his observations and opinions. But the NFL (along with the NBA and MLB) have strict rules that forbid tweeting during games. That didn’t stop Ochocinco from tweeting during a preseason game last August. The tweet cost him a cool $25,000.

3. Mark Cuban. The Dallas Mavericks owner has been fined more than $1 million dollars by the NBA over the years, and some of that money has been a result of his social media usage. For instance, Cuban was fined $25,000 in 2009 for complaining about the refs on his Twitter account.

4. Stephanie Rice. The Australian swimming star gave a tearful apology after she made homophobic remarks on her Twitter account. After her country’s rugby team defeated South Africa’s, she made the unfortunate decision to tweet “Suck on that f***ots.” And she didn’t even put the comma after “that.”

5. Lance Armstrong. In addition to being an alleged doper, Armstrong is also a veteran of the social media controversy sphere. In 2009, Armstrong took to Twitter to go after fellow bicycle rider Alberto Contador. Armstrong told him, among other things, to “drop his drivel.” Contador responded by actually talking to reporters. "[Armstrong is] a great rider and he did a great Tour,” Contador said. “Another thing is on a personal level, where I have never admired him and never will."

Special mention should be made for the infamous “Twitter Hacker” who has (wink, wink) hacked the accounts of several athletes and posted things that they would never ever say. ESPN’s DJ Gallo set out in March to find the Twitter Hacker that affected NBA stars Carmello Anthony, Ty Lawson, and Paul Pierce. He’s still on the loose, so beware, people.
