the blind man doesn't know he has 9 kids

Right on

Rubber and Stick

Husband and wife are waiting at the bus stop with their nine children.
A blind man joins them after a few minutes.
When the bus arrives, they find it overloaded and
only the wife and the nine kids are able to fit onto the bus.
So the husband and the blind man decide to walk.
After a while, the husband gets irritated by the ticking of the stick of the blind man.
As he taps it on the sidewalk, and says to him,
'Why don't you put a piece of rubber at the end of your stick?
That ticking sound is driving me crazy.'
The blind man replies, 'If you had put a rubber at the end of YOUR stick,
We'd be riding the bus, so shut the hell up.'

Stepping out of the shower, the man observes to the wife, "Don't you think my penis is a little bigger?"

"You wish!"

He persists, so she looks more closely. She professes not knowing for sure.

The next morning the man insists his penis is getting larger. The wife measures it with a tape measure to set a baseline.

Each morning for a week the wife measures the man's penis, and each morning it is 1/4 inch longer. By the time they can see a doctor, another week has passed. The doctor schedules "surgical intervention" and asks if either of them has any questions. The wife asks, "How long will he need crutches?"

"Why," the doctor responds, "Do you expect he'll need crutches?"

"Well, you are making his legs longer, aren't you?"
