This old one made us smile:-
"One day my Gramma was out, and my Grampa was in charge of me.
I was maybe 2 1/2 years old. Someone had given me a little 'tea set'
as a gift, and it was one of my favourite toys.
Grampa was in the living room engrossed in the evening news when I brought him a
little cup of 'tea', which was just water. After several cups of tea and lots of praise for such yummy tea, my Gramma came home.
My Grampa made her wait in the living room to watch me bring him a cup of tea,
because it was 'just the cutest thing!' ;
Gramma waited, and sure enough, here I came down the hall with a cup of tea for Grampa, and she watched him drink it up. Hmmm ?!!?
Then she said, (as only a Gramma would know), "'Did it ever occur to you that the only place she can reach to get water is the toilet?"
