Laughter is involuntary. If it's funny you laugh.

One longs to be funny, to make people laugh. Laughter is such a sign of approval, isn't it?

Give yourself a laugh treat

If you did not laugh at least 3 times in a day, then you have missed the best part of your day

If you can't make it better, you can laugh at it.

You can't be satirical and not be offensive to somebody.
