another fun thing to do (especially if you have lots of seasons on dvd) is to keep track of how many glorified extras got reused throughout the years. Like the dude who plays the sheriff in the episode written by steven king about the little girl with the fucked up demon doll that makes people claw their own eyes out also plays the insanely vulgar detective in the episode "Jose Chungs: From Outer Space" that's the one with the Ray Harryhausen monster and Alex Trebek. Oh, and by the way, in the stephen king episode they show scully in the bath tub and she takes her leg out to close the door with her foot and I garauntee you will have an instant orgasm from seeing it. Other than that, the dude that played Dr. Yonichi in the episode where the guy comes back in time as an old man to kill himself and all his research parters cause they invented successful cryogenics which ultimately led to time travel is also a character in the one about the volcanic fungus that bursts out of people's necks. Then, the dude that played Hepcat Helm, I believe his name was, in the episode with the circus freaks (the guy who ran the "tabernacle of terror") also played the wheelchair bound friend of the prison inmate in the first season who had a grudge against Mulder and then got released after they did fountain of youth type experiments on him so Mulder couldn't recognize who he was cause he looked all young and shit again. But ya those are only a few examples and I've barely scratched the surface here. If anyone can tell me which other episode the black lady who played the hostage negotiator in the second part to Dwayne Barry was also in I'll be eternally grateful. It's been driving me crazy. I know it was abit part as a deadpan morgue attendant of some sort but that's all I remember. Ya I'm a huge ass nerd hahah...
