VIDEO: LITTLE HOUSE ON THE PRAIRIE Cast Reunite on 'Today'

To mark the 40th anniversary of "Little House on the Prairie," the cast of the popular drama series reunited on this morning's TODAY and shared tears, laughs and some surprising stories.

Check out the appearance below!

Joining today's reunion were series stars Melissa Gilbert (Laura Ingalls), Karen Grassle (Caroline "Ma" Ingalls), Melissa Sue Anderson (Mary Ingalls), Lindsay Greenbush (Carrie Ingalls), Dean Butler (Almanzo James Wilder), Alison Arngrim (Nellie Oleson), Matthew Labyorteaux (Albert Quinn Ingalls) and Michael Landon Jr. (son of the late star who played Charles "Pa" Ingalls).

"I got tears in my eyes," Grassle confessed after watching a clip that introduced the segment. "First of all, I'm sitting here with these three daughters, really for the first time since (Michael Landon's) funeral (in 1991). And then to see them come running (in the clip) ... just kills me. ... I'm not really that sentimental."
