Chad Ochocinco has been fined $20,000 by the NFL for flashing a dollar bill at an official during a replay challenge -- a joking attempt at what the Bengals receiver referred to as a "bribe" -- in last Sunday's Cincinnati-Baltimore game.

In the third quarter of the Bengals' eventual victory, Cincinnati quarterback Carson Palmer completed a 15-yard pass to Ochocinco. Baltimore challenged the call, contending that he was out of bounds, and the Ravens won the challenge.

While the play was under review, Ochocinco held a $1 bill at his side. The official appeared aware of his antic and waved him off.

"I was just being me," Ochocinco told the NFL Network after the game. "I wasn't going to do it for real."

According to a league spokesman, Ray Anderson, the league's executive vice president of football operations, fined Ochocinco for violating a rule that "prohibits use of abusive, threatening or insulting language or gestures toward game officials. He was also in violation of Rule 12, Section 3, Article 1 (f) of the Playing Rules which prohibits possession or use of extraneous objects that are not part of the uniform during the game on the field or sideline."
