I might have two:
1.) The Sandstorm, Desert Bluffs edition. The sudden appearance of a new radio host voice was jarring, and the story itself was wonderfully creepy, and not only from Cecil’s narration of the studio’s appearance. Kevin’s overabundance of warmth and delight was unsettling, and his way of omitting truth held a certain malice. Cecil omits truths because he doesn’t know what’s going on, and he announces that right up front. Kevin omitted information because it was all Things We Don’t Talk About Or Else. There was an overshadowing of a terrible threat that made the whole episode give me shivers.
2. Street Cleaning Day, just because of the ridiculous level of panic and drama given to the presence of the street cleaners. Just… drama everywhere, and it was hilarious. I dunno, I listen to Street Cleaning Day when I just want to laugh.
