Bosco's business style appears to be based around overcharging for any item so he can afford his elaborate high-tech, homemade security systems, as well as selling his personal brand of "BoscoTech equipment", which are generally rudimentary at best, but cost extraordinary amounts of money (like a hundred million dollars for a "Truth Serum" - which turns out to be a bottle of Vodka). Throughout Season One, his paranoia causes him to dress up as different people (such as an English man, a French man, a Russian man, and even his own mother). These disguises usually involve nothing more than Bosco wearing a hat or make-up. He still wears his ordinary clothes, and even his name tag saying his name.
At some point between Seasons One and Two, Bosco uses the money he made selling his BoscoTech items to Sam & Max to equip his store with even better security measures and various detection apparatus. He also covers the windows in aluminum foil, dims the lighting to a red glow and stops selling things. This is mostly because of his newfound fear of being abducted by T.H.E.M., which turns out to be justified as they do abduct him sometime between Moai Better Blues and the end of Night of the Raving Dead. He is found relatively easily, but it takes Sam & Max Chariots of the Dogs and a significant part of What's new, Beelzebub? to completely save him.
Bosco has a peculiar relationship with his mother, Ms Bosco. In Chariots of the Dogs, Bosco inadvertently travels back through time and causes a mess in her store. While Sam & Max manage to repair most of the changes to history this causes (including Bosco being a cow), this nonetheless makes her seek revenge and enlist Flint Paper to try to track him down, unaware that he is actually her own future son. The truth about all of this only comes out after she dies in What's new, Beelzebub?. At the time she also mentions how she sent Bosco an alarm clock every Christmas, which he always took to be a bomb and promptly disposed of.
One of the first test-tube babies, Bosco was "born" in a machine, rather than his mother's womb. It is implied that his father is John F. Kennedy, which may explain his paranoia and obsession with conspiracy theory.
In the time before Sam & Max: The Devil's Playhouse, Bosco has traveled with Bluster Blaster to Las Vegas along with the rest of his unspent money that Sam and Max had given him in Season 1. In the fourth episode of the season, Bluster Blaster can be found at the harbour and reveals he has a letter from Bosco for his mother, which turns out to be a request for 20,000 dollars to resolves his problems with the casino owners. Bluster Blaster then says that he doesn't want to deal with a person like Bosco ever again.
Bosco is smart, loud, and completely paranoid.

Ogie Banks (Sam and Max Save The World Remastered)
- Whenever Sam randomly ask Bosco what he has in his store, he simply says "Nope.", But he'll eventually say yes to the question. In the sixth episode (where he's disguised as his mother) he actually has some stuff that could've been used for Sam and Max's previous adventures.
- Sam and Max believe he uses the word "Foo!" often even though he has never said it.
- His biggest fear is having to perform on stage naked (though really he likes to be naked, while his real fear is being watched due to his paranoia). In "Beyond the Alley of the Dolls", Bosco stayed in Vegas to earn money as a male stripper.
- In the Remastered game, Bosco is voiced by Ogie Banks possibly due to controversy over his previous voice actor being white impersonating a stereotypical black man.
- Due to some dialogue changes, Sam and Max still refer to him as "Sissypants" in episode 3, this was probably to make the duo make fun of his disguise.
- In the original dialogue (disguised as his mother), when you ask him to rub the unicorn, he'll say "I'm not that kind of woman!", in the Remastered he will gasp while the subtitles read "Well!".
