Three guys go into a pub for a few drinks. They've been at the pub for about an hour, and they are having a good time. All of a sudden, a man at the other end of the bar stands up, points at one of the guys and shouts, “Oi, I've shagged your Mum.” Not wanting any trouble, the guys ignore him and carry on their conversation and drinking. Again, about 30 minutes later, the man stands up and points at one of the guys and shouts, “Oi, your mum's soocked me cock!” The guys are a bit offended, but stay quiet as they are having a good time and don't want to ruin things. After another 15 minutes, the man stands up again and shouts out, “Oi, I've shagged your Mum up the arse!!!” This is too much to take, and one of the guys stands up and shouts back, “Dad, you're drunk! Now go home!”
