What is it with aliens and butts? This week, the guys take a probing (!) look at the supposed UFO crash in Roswell, New Mexico in 1947. Along the weird and winding way, they encounter Joseph Stalin, Josef Mengele, a bunch of mixed alien parts, and tiny Russian children plummeting from the sky. No one wants to feel alone, but if these are our interstellar neighbors, I'll take loneliness!
