Do you think the homeless people who have signs saying...?

I personally believe in karma, so whenever i see a homeless person i give them money no matter what their sign says. So to me it doesn't matter. I once saw a show where this guy purposely tried to look homeless, and had a sign that sed "homeless and hungry" and then an hour later held up a sign that Sed "homeless and need a beer" and he got more money from the second sign.
