the husband and the blind man decide to walk

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 sound 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 would’ve put a RUBBER at the end of YOUR stick, we’d be in
the bus right now …  so shut up !
