Mary was visiting her “American grandchildren”, Everett and Eliza, during the week before she passed away.  One afternoon 6-year old Everett told a “knock-knock” joke that he had rehearsed for her:

Everett:         Will you remember me tomorrow?

Granny:        Yes of course I will.

Everett:         Will you remember me next week?

Granny:        Yes, dear.

Everett:         Will you remember me next month?

Granny:        For heavens sake I should hope so.

Everett:         Will you remember me next year?

Granny:        (with a bit of annoyance).  Yes Everett.  Now what is it?

Everett:         Knock-Knock.

Granny:        Who’s there?

Everett:         AHH!!!  You forgot me already?!?!?

I have never seen Mary laugh as heartily!  She didn’t see the punch line coming, which was reason for great delight for her and for Everett!
