I can only report what I was told by the couple during the interview. Sadly, I was able to verify that the wife was abducted, but reports of alien sexual practices and the benefits of couples therapy are too subjective and open to interpretation.
Based on my own abduction experiences, however, I can say for a fact that I never saw one smile, laugh or even indicate any awareness of humor, irony, sarcasm, or even leg pulling. Perhaps this is because they are telepathic and nuance is communicated with message. Or because they have no detectable funny bone. (This was verified in the deleted scenes of FOX’s Alien Autopsy.)
