Sid Ceaser proposed to his girlfriend Sara Prindiville in one of the most creative marriage proposals I have seen to date. He ordered custom Muppets from FAO Schwarz in New York City that resembled both he and his fiance Sara, and used the muppets to create a short video/fake trailer detailing thier jounrey as a couple. Apparently Sid and Sara went to the movies, in which point Sid snuck out to insert the trailer between regular previews and well she said no. No just kidding. She said yes.
Sid also documented the entire process over on his website. You can see the video below.
