There are so many things of humour in the world that are not hurtful...why not use them. Maybe I am thinskinned, but there are days that if I hear ONE more dumb blonde joke, I will scream. Being the constant butt of inference that you are dumb/greedy/lazy, gets old, very fast. The first 50 times, I can laugh. The subsequent times, I grit my teeth. Chances are, there are jokes that offend every one of us here. I just find it needless to have humour at someone elses expense.
