Bob is working out on a stationary bike picked up from the trash, but while taking a shower, notices that he's losing hair in his mustache.
While nitpicking minor and non-existent crimes, he meets Linda on the streets singing about Hugo.
A battle ensues in which RoboBob is killed, with Linda putting his robot mustache on a cactus.
After failing with all of them, Bob goes to an automated carnival attraction, The Swami, only to find it under repair, and instead asks the repairman for a mustache.
Tina's story tries to make her parents end up together but no scenario works at first, and soon she imagines that Linda would have married Hugo, had three Hugo-versions of the children, and run a hot dog restaurant in the manner of Bob's Burgers, while Bob has become a bitter health inspector like Hugo in the real world.
The family is disturbed by this story, and Tina accepts that if Bob hadn't had his mustache, Linda would not have canceled her engagement to Hugo and she would have married him, and also that there is no such thing as fate, just randomness and chaos.
