A blond loses his check book, so he goes to the bank 2 days later to report it. Bank manager: I warned you to be careful with your check book, because anyone can forge your signature. Man: "I'm not a fool. I already signed all the checks so there is no space to forge my signature!"
You have to be careful these days. I was walking down this creek yesterday and this guy suddenly pulled out a scissor, but luckily I was agile enough to reach into my pocket and pull out a rock because if I had pulled out paper, man I would’ve lost.
