Full House Cast Sings Theme Song, Instagram Goes Wild [VIDEO + PHOTOS]

No matter how old I get, I still always want to see the cast of Full House hanging out, especially if that includes breaking into song.

Most of the cast, minus the Olsen twins of course, got together for Full House creator Jeff Franklin's birthday

Thank goodness, Aunt Becky (Lori Loughlin) and Kimmy Gibbler (Andrea Barber) posted it all on Instagram for us.
