Weird Science - Season 5 Episode 9

Wyatt keeps going out on dates, but none of the girls are right for him. Lisa zaps up a Bride Detector, that will go off when your future wife is close to you. Wyatt's future wife is sitting right in the Java Man. Chett tries to use the detector to make Lisa think she'll be his future wife. So, he uses an engineering manual, and makes the detector go off when it's near Lisa. Unfortunately for him, Lisa knows all about what he's been up to, and strings him along. Wyatt loses his future wife after being too serious about the whole thing. And after it's all over, it turns out that the Bride Detector never really worked.
