How can you believe anybody that makes wild claims like he does?
He wasnt a licensed engineer, he just happened to be emptying the trash in the office where they were discussing the lunar vehicle and one of the guys asked Jim, "HEY, you know a lot about electrical wiring, dont you"?
Jim says, "Well, shoot ya, I made me a garage door opener once. Watcha need fixxed?"
"Well, come outside in the secret lot in back and have a looksee at our secret lunar vehicle thing. It aint runnin right, we think it might be an electrical problem."
After 10 minutes of tinkering around with it, Jim figgers out the problem. Those nincompoops wired the discombobulator to the thingamajig and caused a short which made the durn defrosters turn on when you hit the spacewarp button.
Jim fixes it, she's runnin like new!
Next thing ya know, he's telling pregnant women to drink pulp bleach
