Sid Ceaser gets bonus points for romantic creativity. The New Hampshire photographer really wanted to do something special when he proposed to Sara Prindiville, so rather than just buying a million candles and rose petals or something, he went full Muppet.
Ceasar bought Muppet versions of himself and Prindiville online, made a movie trailer, and then got a theater to play it before a movie that the happy couple attended. The whole filming process and story is detailed over on Ceaser's blog.
For the record – unlike the whole "Chris Brown wedding dance," The A.V. Club totally supports copycatting this effort.
