It's been five years since the last time Greg Jennings had more than 1,000 yards receiving in a single season. It was also the same year he won a Super Bowl with the Green Bay Packers. He was one of the most recognized wide receivers in the game then, but things have changed since.

Jennings, now with the Miami Dolphins, went undercover at Modell's in Times Square, as several athletes have in the past -- DeSean Jackson and Danny Woodhead being two of them. Sadly, no one noticed that "Ace," Modell's sales associate, was actually Jennings.

Well actually, one (literally) huge Packers fan did ... and quoted Jennings' Twitter hashtag, #BeGreat, as he looked down upon him.

Watch the full clip below, which includes Jennings stealing a basketball from a young shopper.

Had Jennings pulled this trick five years ago in Wisconsin, everyone would have known who he was. Unfortunately, he's suffered a severe drop in production in recent years and isn't as recognizable as he once was.

Oh well, it still made for a great undercover video.
