A drunken man walks into a biker bar, sits down at the bar and orders a drink.

Looking around, he sees three men sitting at a corner table. He gets up, 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.
