Keith and Lauren are on this HGTV Designed To Sell episode, "A Project Too Demanding," as "buyers" at an open house for one of our agent friends. This was filmed in the middle of 2009 and finally aired at the end of 2010. The Silbermans are on at the end of the show and never realized that the people attending the open houses on this show are usually agents until they took part themselves. The open house starts about 19 minutes into the show. They're on at 19:53 seconds into the show.
