Humour and wisdom is one of those great combinations because for the following reasons:

1. When people laugh, they relax and they open up. They are more receptive to your ideas.

2. Humour allows for great juxtaposition.

3. People are more likely to accept your insight and sage like wisdom if you can laugh… at yourself.

There are very few things to get people drop their guard more than humour. If you want your audience to consider a new perspective, one of the best ways to get them to open themselves up to it is to first get them laughing.

But if we make things too funny people may take it jokingly missing the serious note in it.

So the best thing to be done is to proving your point in a serious as well as humorous note so that you do not set them yawning but leave them craving on every word of yours.
