Republican joke

I was busy for the past week, so the only update is this job I heard this morning. I was told it is a true story.

On a party, a guy asked a little girl (whose parents are liberals) what she want to do after she grew up. The girl said she want to be the president of US so she can give all the homeless people a house. So the guy told the girl, she can help the homeless people now, by going to his home, cut his lawn and in turn, he will give her $50, which she can give to a homeless man to be his home found.

The little girl asked "Why can't the homeless man do that for you and you give him the $50?". And the guy said "Now you are a republican".
