A towel for two

I feel like a wet fish  tonight
Do you want a towel?
Why, do you like them?
Who do you mean?
That’s statistics.
Only elementary.
Maybe it is simple to you but not to others
Which others?
Well,I don’t know. People of average intelligence
Mine is so low I am an imbecile
Well, what a surprise
It was to me,I didn’t know before I went to Oxford, fortunately
How on earth did you get in?
I went on the train.
But did they not test you?
I said I’d cry if they rejected me
So what happened?
They asked me to teach some undergraduates
Just like that?
Yes,I was shocked myself but the maths was not so bad
Did you get Teach Yourself Analysis?
I didn’t know you could
Could what?
Teach yourself
Who taught you?
It was like talking,I just picked it up
Well, it’s a  puzzle
Not after you pick it up
Unless it’s a jigsaw puzzle
Well, where is the wet fish?
In the river
What river
The Dee.
Chester is on the Dee
Sto p accusing Chester.
What, is  being on the Dee wrong?
Probably with Boris ruling it will be
What does he know?
Nothing,That is the problem
Mathematics has problems
Not like this.
So one could say it’s easier than living
Well, you can’t so it when you are dead
You can’t live when you are dead
As far as we know.
Do we need a Venn Diagram?
They make me feel faint
That’s lack of food
Is it really? I thought food was just entertainment
How can  you be so stupid?
It is normal for imbeciles
Yet you taught linear algebra
We should have done it elliptically
You telling  me?
Cryptically
