Take, for example, the time they made former No. 1 overall pick Tim Couch cry, or when they cheered Derek Anderson after he suffered a season-ending knee injury.
On Tuesday, Anderson was released by the Browns, ending a four-year run with the team that included a trip to the Pro Bowl in 2007 and a steady decline over the following two years.
Still stinging from hearing fans cheer his injury, the 26-year-old quarterback sounded off about the orange-and-brown faithful.
In an e-mail to Jeff Schudel of The News-Herald, Anderson said the following:
"The fans are ruthless and don't deserve a winner ... I will never forget getting cheered when I was injured. I know at times I wasn't great. I hope and pray I'm playing when my team comes to town and (we) roll them."Ouch. The next step for Anderson, of course, is finding a new team that will give him an opportunity to go into Cleveland and "roll" the Browns. Might be easier said than done, as Anderson has struggled mightily over the last two seasons, completing less than 50 percent of his passes and posting a passer rating under 60.
He played eight games in 2009 and recorded the lowest rating in the NFL, throwing only three touchdowns to 10 interceptions.
ESPN's Adam Schefter reported that the Arizona Cardinals will be "major players" for Anderson and could eventually sign him.
In case you're wondering, the Cardinals aren't scheduled to play the Browns until 2011.
UPDATE: Anderson has since apologized to Browns fans.
