Dog Day Afternoon!

Dog's.

Yes, dog's again.  What? Have I not mentioned that I have three dog's?

Oh, come on!  I must've done.

Look!  I did, a'right!!!

Anyway, whether I have or haven't is irrelevant, because I have ... got three dog's. 

Oh bum!  Ya see?  All that prevaricating (you, not me) has made me forget my subject for today.

It doesn't matter. I'll tell you a joke instead.

An old was taking her dead cat to the pet cemetery. 

As she boarded the bus, she whispered to the driver "I have a dead pussy".

The driver pointed to the woman in the seat behind him and said, "Sit with my wife. You two have a lot in common".
