Funny / The X-Files: Fight the Future

• Mulder's "panic face", which is entirely deadpan and blank. And the Call-Back Lampshade Hanging when Mulder is trying to figure out what to do about the bomb a few minutes later.
• Mulder being bored on his assignment in Dallas:
  "Maybe we should call in a bomb threat to Houston. I hear it's free-beer night at the Astrodome."
• After Mulder sneaked out of the hospital after his gunshot wound in Byers' clothes, he tosses his jacket onto the street without a second thought while he runs away. It may be a little thing to notice, but it is funny.
