Looks like Penn State just can't seem to catch a break. They're in the hot seat once again, not for child abuse, but for racism.

Members of the Chi Omega sorority at Penn State are under fire after posting pictures from a Mexican-themed "racist" costume party.

A Penn State sorority has become the focus of an investigation after a racist Mexican-themed party picture was posted to the Web, according to the independent Penn State blog, Onward State.

The picture, said to be taken around Halloween, shows the women dressed in sombreros and mustaches. Some of the women held signs that read "Will mow lawn for weed + beer" and "I don't cut grass I smoke it."

The photo was posted on Tumblr and Facebook, where Onward State was able to identify the women tagged in the photo as members of the Chi Omega sorority on campus.

Jessica Riccardi, the president of the Nu Gamma chapter of Chi Omega, confirmed to the student publication the Daily Collegian that the sorority is under investigation. Riccardi also issued an apology.

"Our chapter of Chi Omega sincerely apologizes for portraying inappropriate and untrue stereotypes. The picture in question does not support any of Chi Omega's values or reflect what the organization aspires to be."

I get that this party theme may not have been in the best taste, and that the signs were overkill and a stupid idea. And the fact that this took place at Penn State is unfortunate, since their reputation is still in the crapper and the last thing they need in bad PR.

But honestly, people need to chill out and learn how to take a joke. I really don't think these girls were purposely trying to be hateful and racist. They probably thought they were being cute and funny, as most college students do when they do stupid things.
