Did the Green Bay Packers lose to the New York Giants because of lousy tackling? Poor officiating? No, it was because Green Bay Packers’ Fan Casey Lewis used sparkly nail polish.

Sound ridiculous? Well, Lewis typically paints her nails in Green Bay Packers’ green to help her team win. She also typically wears an Aaron Rodgers jersey. But last Sunday Casey Lewis did the unthinkable. She put on a Clay Matthews jersey and painted her nails sparkly. Obviously, she caused the Packers to break down and lose to the Giants.

In an interview with the Star Tribune , Casey admits that she’s not sure why she changed her routine. Casey said:

“That’s a question I’ve really been struggling with lately. Megan (her sister) said Clay’s your man, you have to support him. So I made the decision to do that, and I really regret it. But it was a jersey I got for my birthday.”

Michael Rand, who conducted the interview, tried to convince Casey that her nails had nothing to do with the Packers loss. But Casey isn’t so sure. The Packers fan said:

“You can keep telling me that, but I don’t know if I’ll believe it.”

And Casey isn’t the only one blaming herself for the loss. Clay Matthews posted a link to the superstitious Packers fan’s now infamous video, saying “D_mn you and your sparkles!!”

Here’s the video.

If you’re wondering, yes, Casey had a few drinks before crying about the Packers loss. Her sister, who posted the video, writs on Youtube:

“Casey’s (my sister) reaction after we left the bar after the packers lost to the giants in the playoff game. we die for our team!”

Do you blame Casey Lewis and her sparkly nails for the Packers loss?
