The cast of "Mean Girls" get it. They get that fans from all over still celebrate the iconic movie every October 3rd and guess what... It's October 3rd. But this year, the cast reunited on social media for more than just a throwback pic. They posted a video driving the attention to the tragic events that took place in Vegas just one day prior. They urged fans to donate to a GoFundMe page dedicated to donating funds to families of those affected by the shooting in Las Vegas.

We may be the "groolest" fans, but this is a pretty "grool" too.
