Jimmy has a condition called Auto-Brewery Syndrome (and a wicked beard too). What's ABS you ask??
Before we get explaining, I'd like you imagine something...
Imagine you're driving home (or anywhere for that matter) and get pulled over by the police. You get breatherlized and it comes up with a reading, "but I havn't had any alcohol today officer!".
This is the type of situation Jimmy finds himself in all the time because the high levels of yeast in his stomach produce intoxicating quantities of alcohol when he eats carbohydrates. The yeast turn these carbs into alcohol through endogenous fermentation. This is what we call Auto-Brewery Syndrome.
Though the condition is reasonably rare, it was first discovered in Japan in the '70s and it is believed (but not exclusive to) that people develope the condition after using antibiotics for long periods of time.
Treatment comes in the form of antifungal medicine like fluconazole and a strict diet of low sugars and carbohydrates.
So next time you go for a serve of chips at the local take-away, think of those poor souls that can't enjoy the awesomeness that is hot chips and gravy... Or is it a cheap way of having a few without having a few?? I'll let you be the judge.
