Tears, Jokes, and Laughter

I went down to Grammie and Pa's today after work. I was so tired it's amazing I didn't fall asleep reading Harry Potter. When I finished, I took a nap while AJ got Grammie up. Then, AJ and I went over to the market place to get Greek food for dinner. After Pa, AJ, and I had eaten I went down to say good bye to Grammie.
I said, "Good bye. I'm going home and going to bed."
Grammie said, "Good bye. You need to go home. AJ will take care of you when we're no longer able to." At first I thought she thought I still lived with them, but then she started to get teary eyed and I realized she meant when her and Pa had died.
I said, "You've done a good job taking care of me."
"That's a nice compliment." Then she said, "Where's my little elephant?"
We had forgotten to give her animals back after she got up. I gave them back and was getting a little teary eyed myself. My nose started to run and I told her it was her fault.
Her reply was, "You give me Monk and I make your nose run."
She apologized for getting teary eyed and crying, but I told her not to worry.
To lighten the mood a little I decided to tell her a joke. I knew how much she loved the blonde jokes, so I told her about the blonde getting fired from the M & M factory for throwing out all the "W's." Grammie laughed so hard. Then, I started laughing because she couldn't stop. AJ came into the kitchen and wanted to hear the end, so I retold it. AJ stood there with a look on her face that said she clearly didn't get the joke. Grammie was still laughing as I explained to AJ that an upside down M is a W. She still didn't get it which made Grammie and me laugh even harder. Finally, after lots of explaining to AJ and telling Grammie that AJ was still thinking did she get it. Grammie's reaction? "That's choice!" I told 2 more blonde jokes and then I stopped because I was afraid Grammie would hurt herself from laughing so hard. AJ said that Grammie might be up all night thinking about the jokes. I'm so glad I thought of them.
P.S. Wednesday I read If You Give a Mouse a Cookie and If You Give a Pig a Pancake. Grammie loved them both. She looked at each picture for quite awhile before I turned the page. Any suggestions as to what little fun book to read next? I was thinking something of Dr. Seuss.
