joke, sweet without seed

Grandma of a boy don’t like eating medicine. So the boy went to the doctor and asked what he could do. The doctor tells him a trick.
The boy came into home with some sweet and put the medicine inside it and gave it to Grandma to eat the sweet as she likes it very much.
After eating sweets the Grand son told to Grandma, “I am very happy to see that you have eaten all the sweets.”
Grand Ma replied, “Yes I have eaten all sweets but I didn’t like the seeds inside them and removed all seeds from it.”
