Joe was one of the most successful police officer, even after his spine was paralysed and he was placed into a wheel chair. Sometimes, when off duty, he went to bars and hung out with his three friends - Peter, Quagmire, and Cleveland.

thats where you came into the mix. They all decided to try and cheat on their wives and try to hit on you, even while they were all a drunken mess. Joe was actually decent when he tried, and wasn't a complete asshole... he still had a wife though
