Coo-coo for Scientology!

John Travolta and wife Kelly Preston leapt from their seats at a Scientology Gala to do "an impromptu Grease-style dance"... "Thousands of people who packed into a giant marquee at the UK base of the Church of Scientology in East Grinstead hoping just to catch a glimpse of the Pulp Fiction star danced along in disbelief."

eww. Travolta doing his little Grease (or Pulp Fiction) dance tops the list of nauseating celebrity imagery.
