A drunk walks into a biker bar, sits down at the bar and orders a draft beer.
Looking around, he sees five 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 she was wearing a tight sweater. Man, she has big boobs!'
The biker looks at him and doesn't say anything. His buddies are confused, because he is one bad biker dude and would fight anyone.
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 doesn’t say a word.
The drunk leans on the table one more time and says, 'I'll tell you something else, boy, your grandma loved it!'
At this point the biker gets up, takes the drunk by the back of his coat, looks him square in the eyes and says...
'Grandpa, you need to go home, you're drunk'
