This happened six months ago, but the video that was just uploaded a few days ago certainly qualifies it as gem-worthy.
Rylynn Riojas is in need of a heart transplant.
The two-year-old has been at Children's Medical Center in Dallas on an artificial heart device waiting for that new heart.
But the one she's got is filled with love for the Aggies, and especially the First Lady of Aggieland, Reveille.
Rylynn keeps a Rev doll with her at all times, so when staff at Children's called up A&M, Reveille and her handlers came to Dallas to brighten her day.
The Aggie Yell Leaders also stopped by to greet one of their biggest fans.
