INT. STAGE. NIGHT.
A VENTRILOQUIST IS ON STAGE WITH HIS DUMMY.
VENTRILOQUIST:
I'm afraid the dummy tonight is a little worse for wear.
VENTRILOQUIST TAKES A MANKY CHILD'S DUMMY OUT OF HIS POCKET.
VENTRILOQUIST:
You wouldn't give that to a dog.

I think the joke is simply that he has a baby's dummy instead of a normal dummy.
Ah well, thanks anyway. I'll stick to talking toilets.
I have to say the talking toilets was brill!
I think there is some milage in the above - I think it just needs a little play about with.
