Melissa McCarthy and Ellen Change the Lives of a Mother/Daughter Duo with a Game of Beer Pong

The actress stopped by "The Ellen DeGeneres Show" on Monday to promote her new mother/daughter college-themed movie, "Life of the Party." Ellen called up audience member and student Jaida Jackson to come play some beer pong with Melissa, but when Jaida revealed she was only 19, Ellen quickly called up her mother, Chassidy Jackson, to play on her behalf.

Melissa slipped on an apron covered in six beer-filled cups, and Chassidy was given 30 seconds to toss ping pong balls into the cups. For every cup Chassidy made, she was given $1,000. She made all six -- likely leaving Melissa just shy of tipsy -- but that was just the tip of the iceberg.

"Here's the thing, we brought you down because we knew a little bit more about you," Ellen revealed to the Jacksons. "That's why you're here."

What Ellen already knew: Chassidy raised Jaida on her own and has been struggling to put her through college. She's taken out $17,000 in student loans and has spent her life serving others. Chassidy's dream has always been to go back to college, but she hasn't been able to afford it -- until now.

On behalf of Shutterfly, Ellen presented Jaida and Chassidy with a $25,000 check.

"There's one more thing," Melissa added. "'Life of the Party' was so inspired by your story, what you did and how hard you worked, that we also want to give you $25,000 more."

The final surprise came when Melissa gave the ladies an additional $25,000 on behalf of her and her husband, Ben Falcone.
