'Full House' Reunion! Watch Bob Saget & Cast Sing Theme Song From Beloved Show: But Which Cast Members Missed Out?

It's a Full House reunion! The stars of the beloved '80s-90s sitcom reunited for the birthday of Jeff Franklin -- the creator of iconic cultural touchstone -- to sing the TV show's equally iconic song "Everywhere You Look". John Stamos (Uncle Jesse), Bob Saget (Danny), Lori Laughlin (Becky),  Candace Cameron Bure (DJ), Jodie Sweetin (Stephanie) and Andrea Barber (Kimmy Gibbler) joined the song's original singer Jesse Frederick in an excellent rendition of the theme song. But why did Dave Coulier (Uncle Joey) and the Olsen twins -- Mary Kate and Ashley -- miss the celebrations?

As Entertainment Weekly report, the cast were back together "to celebrate the birthday of the show's creator, Jeff Franklin." They serenaded Franklin with a sweet rendition of "Everywhere You Go," with everybody joining in on the chorus.

Missing out on hanging out with Uncle Jesse (Stamos) Danny Tanner (Saget), Becky Katsopolis (Loughlin) DJ Tanner (Cameron), Stephanie Tanner (Jodie Sweetin) and Kimmy Gibbler (Barber) were Uncle Joey (Dave Coulier) and Michelle Tanner (played by twins Mary Kate and Ashley Olsen).  

As US Weekly point out: "No Olsens? How rude!"

Apparently they had other plans? 

I feel like whenever anyone talks about the "Full House" cast, it's a given that the Olsen twins aren't included
