(CBS News) Karen Klein wasn't having the best of days when she was recently bullied by a bus full of students from Greece, N.Y.
The middle school students teased, taunted and threatened the 68-year-old school bus monitor. The incident was caught on video, posted on YouTube, and instantly went viral -outraging viewers.
The students, between ages 12 and 13, can be heard heckling Klein - calling her "a troll" and asking aloud why there's water running down her face.
"I'm crying," Klein said on the video. "Unless you don't have something nice to say, don't say anything at all."
Klein, who drove a bus for 20 years, kept her cool. But she told CBS affiliate WROC one comment really hurt.
In the video, a student is heard saying, "But you don't have a family because they all killed themselves because they didn't want to be near you."
"Something about me being so fat and ugly your kids probably should commit suicide," Klein told WROC. "I don't think they knew my son had....I wanted to punch them is what I wanted to do. So that's why I laid back, tried to ignore it. Because I really wanted to hurt them, you know? You can't do that!"
An online viewer started a fund to send Klein on vacation, with a modest goal of $5,000. But as word spread online, the fund exploded. So far, it's raised more than $140,000 and is still growing.
Klein said she doesn't want the students to be criminally charged. But she wouldn't mind seeing them grounded all summer. And if nothing else, she just wants a simple apology.
Correction: An earlier version of this story stated that the vacation fund for Klein was started by a family friend., online fundraiser Max Sidorov has no connection to Karen Klein.
