An elderly couple visits the doctor to see the results of their clinical tests.
The doctor tells them that the results have come out very well, their health is very good, but the couple tells him that both have the big problem of forgetting things; the doctor recommends that they write things down so they don't forget them.
Comfortably seated in the living room of their house, he gets up and tells her that he is going to the kitchen, she asks him to bring her a scoop of snow/ice cream
the husband…ice cream, fine, I'll bring it to you.
She----but write it down so you don't forget.
He----how could I forget to bring you ice cream.
She----but I also want some raisins on top, write it down; he refuses to do so.
She----write it down, because I want sprinkled nuts on top, write it down.
He----no, I can't forget that so don't insist, I'm not going to write it down.
He says it very convincingly and goes to the kitchen.
And he comes back with a plate with 2 fried eggs with ham and hands them to his wife.
She---you forgot the toast.
