I was watching this episode and found it to be just as stupid if not more so than "Janet Wigs Out." It's like a Stepford Wife switch was flipped as soon as Terri sees Jack wearing the mustache. Very similar to when Janet dons the blonde wig and suddenly turns into a mean, conceited bimbo---so out of character.

The Regal Beagle scene toward the end of the episode between Terri and Jack is super funny, though. And I think this is the only time we see Larry really succeed with a woman!!

Yeah it's pretty ridiculous how Terrinsuddenly saw Jack in a different way with the mustache, its kind of in a way like Superman's disguise of wearing eye glasses as Clark Kent.
