After a short time out on the lawn, Grandma started leaning off to the right, so some family members grabbed her straightened her up, and stuffed pillows on her right. A short time later, she started leaning off to her left, so again the family grabbed her and stuffed pillows on her left.
Soon she started leaning forward, so the family members again grabbed her, then tied a pillowcase around her waist to hold her up. A grandson, who arrived late, came up to Grandma and said, "Hi, Grandma, you're looking good! How are they treating you?"
Grandma took out her little notepad and slowly wrote a note to the grandson...
"They won't let me fart."
