"Knowing that Cincinnati wide receivers Terrell Owens and Chad Ochocinco have dubbed themselves Batman and Robin, Buffalo Bills wideout Stevie Johnson came up with a clever way to counter the Bengals' dynamic duo.

After scoring a touchdown in the third quarter Sunday, Johnson lifted his jersey to reveal a T-shirt that read, "Why So Serious."

If you're a movie buff, you would know that line came from Batman's arch-nemesis, the Joker, in "The Dark Knight."

"It was something fun," Johnson said. "They play the Batman and Robin thing, so I wanted to come in and have the persona of the Joker and just have fun with it. I'm going to get in trouble for it, though."

Indeed, Johnson was informed that he would be hearing from the NFL in the next day or so. The way he's playing, perhaps the Bills should pay the fine, no matter how much it is.

The third-year pro continued his remarkable breakout season Sunday with eight catches for 137 yards and three second-half touchdowns, including the go-ahead score, in the Bills' 49-31 win over the Bengals.

Johnson, who entered the season with only 12 catches and two touchdowns, is compiling numbers rarely achieved by a Bills receiver. He became the first player in team history with two three-touchdown receiving games in one season and his nine touchdowns is two shy of the club's single-season record set by Bill Brooks in 1995.

Only five Bills receivers have ever scored more than nine TDs in a season, the most recent being Eric Moulds, who had 10 in 2002.

Johnson, who leads the Bills with 52 catches and 728 yards, refuses to take much credit for his breakthrough campaign.

"I've always expected to play big in big games," he said. "But it definitely wasn't all me. It was the coaches, first of all, for calling those plays. They call the right play and at the right time. And then, it comes down to [quarterback Ryan] Fitzpatrick once again. He's putting the ball wherever he wants to. And we know he's going to throw it around, so we don't want to make him look bad. You got to make those plays.""
