Pondering. It is mans' way of passing valuable time, over something nonsensical.

Ladies, you should try this. When you are with your man and you see his eyes glaze over, say to him, "TELL ME WHAT YOU ARE THINKING, NOW. IMMEDIATELY"

Be prepared for the most extreme, nonsensical reply.

OK, having said that, I was standing in the park, the other day, pondering on why a frisby gets bigger, the closer it gets.

Then it hit me.

Funny .

And the pun word here is: hit.
