The Simple Fact is, I Am Dim

Can't get away from it, the facts of the matter are plain, even to a blind man. (Am I allowed to say that in these days of political correctness gone mad? I know I can't say Lesbians any more, I have to say "Ladies in sensible shoes.")
Ha! They are all looking down at their feet now and whispering to their friends, "Would you call these shoes, sensible?"
To get back to the point, I am basically dim, can't be denied.
I was going for a chat with the twins and was warned by a well-meaning idiot, "Watch them, they can turn nasty after a drink."
They are lovely really, Angie and Tishy, lovely ladies.
So, our hero, (that's me for those dimmer than I am) sits down between them and I put my arms around them, one arm each. Well, any more would be an extravagance and show favouritism. So, we are having a chat and as is my wont, I was very forthright with my words. They chased me with a view to reorganising my face for me. There was a lot of laughter, but that was the twins, I was busy screaming.
So, when they let me go and returned to stirring their cauldron... I mean to say, all I said was, "Right, when is Cinderella getting here?"
"What do you mean?" asked either Angie or Tishy.
"Well," said I. "We've got the two ugly sisters, I was just wondering..." and that was as far as I got.
Afterwards my pal told me, "I told you!" he said, but, well, you know me, the simple fact is, I am dim.
