Following Hour of Slack #1472 on June 29, Dr. Hal, StangDoe, and Lonecow Dave joined host Dr. Sinister for two hours of Radio Synaesthesia on WCSB -- with callers! This is the first of those two hours. With four voices in the studio and three on the phone lines, this sounds almost like a Puzzling Evidence show: DENSE! Subjects discussed include: Plane crash and saucer seating. When girls call in. SubG: Grief Counselors for Humanity. Brain buttocks. Wisterical women. Major Amos Custard. "Cutting the Onions." Readings from Lovecraft trading cards by monsterwax.com. Aspies. UFO sightings by callers. Mentat Vulcan Jedi Stang. The day Dr. Hal met Ivan. Vampire leprechauns. Hex Day is here!
