Bikie Tolerance

The old fellow is looking like he has a few too many already when he staggers into the biker pub in the town. This is one tough pub and most people cross the road to avoid it.
He wobbles to the bar and orders a beer, sits at the nearest table, then gazes around the room.
His bleary eyes settle on a table in the corner. Seated around it are three men.
He gets to his feet and staggers to the table, leans over, looks the biggest, meanest, biker in the face and says: "I went by your grandma's house today and I saw her in the hallway buck naked. Man, she is one fine looking woman!"
The biker looks at him and doesn't say a word. His buddies are confused, because he is one bad biker and would fight at the drop of a hat.
The drunk leans on the table again and says: "I got it on with your grandma and she is good, the best I ever had!"
The biker's buddies are starting to get really mad but the biker still says nothing.
The drunk leans on the table one more time and says, "I'll tell you something else, boy, your grandma liked it!"
At this point the biker stands up, takes the drunk by the shoulders looks him square in the eyes and says,
"Grandpa,....... Go home, you're drunk.
