Joey becomes an "actor-slash-model" when he appears on print ads for the NYC Free Clinic, as a man named "Mario" who has a Venereal disease.
Joey was presumably born in 1968 as he talks about having turned 13 in 1981.Joey does so, but Sarah really wants to dig in his seafood platter, making him drop his plate to the floor in the process.This makes him explain how "Joey doesn't share food", which she seems to understand.When she arrives, her dessert is pretty much gone; Joey, with chocolate torte all over his face, is at peace with himself, and admits that he's "not even sorry! He is something of an idiot savant in general, but capable of good ideas when the situation arises; this is alluded to in the episode "The One Where Ross Dates a Student", when Chandler, referring to Joey, says "A hot girl's at stake and suddenly he's Rain Man" when Joey suggested Ross work out who among his students called him the 'hottie of the paleontology department' by comparing the handwriting of the note to the handwriting in the class essays.In another example, Joey made up an anecdote referred to as the "Europe story" or the "magic story"; apparently, anyone who hears it will immediately want to have sex with the teller.He let Rachel live with him when she was fighting with Ross, financially supported Monica and Chandler, and helped Phoebe find work when she was unemployed.
He was willing to marry Phoebe and Rachel on the separate occasions he found out that each was pregnant.
This is proven to be effective when Rachel successfully uses the story on Ross.
Joey is extremely promiscuous, often relying on his catchphrase pickup line "How you doin'? He regularly sleeps with attractive women, but can never seem to get into a committed relationship - judging from a conversation he had with Chandler at the latter's bachelor party he seems to regard marriage as depressing and restrictive.
Joey is characterized as a simple-minded but good-natured womanizer who loves food. When asked if he would give up sex or food he had trouble deciding and kept blurting out sex or food, eventually yelling "I want girls on bread! In "The One with the Ride Along", he appears to be saving Ross from a putative gunshot, when it was actually his meatball sandwich that he was trying to save; it just happened to be next to Ross. His greed when it comes to food is also shown in the episode "The One With the Birth Mother" where he refuses to call Sarah the next day.
When Phoebe asks why, Joey explains how Sarah broke his golden commandment on their date - not to share food.
Phoebe's shocked to say the least, but Rachel admits to her how this is who Joey is.
