Ex-NASCAR CEO Brian France says the parody Twitter account "Drunken Brian France" is NOT funny ... and now, he's suing over it.
In the lawsuit, obtained by TMZ Sports, France says back in Feb. 2014 ... John Steele created the account "@drunkbrianf" -- and has been tweeting about the famous NASCAR exec. ever since.
Some of the tweets from the account -- which has more than 18,000 followers -- included ribbing France over his drunk driving case, other jokes about the 57-year-old's lifestyle and general NASCAR talk.
