3 men were trying to convince each other who is the meanest. Few minutes later they see a blind old man trying to cross the street.
So they decide to see who will be the meanest to him.

The first one tells them that he is going to punch him & he did!

The second one decided that he will push him in the middle of the road & between the cars, and he did!

Then they looked at the third guy waiting for him to tell them how is he going to prove that he is the meanest..

" I dont need to do anything, Iam the meanest for sure!"
The third person said

The other two looked puzzled and asked
"How?!"

The 3rd replied"You see that blind old man that you punched & pushed?Well,Thats my dad!" :)
