Oh that's easy. Palin met Greta's husband who happens to be a $cientologist who knows John Travolta. John Travolta was in Look Who's Talking with Kirstie Alley who was in She's Having a Baby with KEVIN BACON!
Bacon was in Tremors with Michael Gross who was in family Ties with Michael J. Fox who was in Mars Attacks with Danny Divito who was in Batman with Christopher Walken who was in Hairspray with John Travolta who knew Gretta’s husband thru scientology....
LOL
this is fun!
