Step 1. Make the pie chart. Save the image.
Step 2.
a) Make a rectangular block of the same color as the pie chart background (I had to take a snip of the pie chart background to do this).
b) Upload the pie chart as a meme. Add the rectangular block to the bottom of it (to make room to add Sweet Brown). Save the image.
Step 3. Upload the second saved image as a meme. Insert Sweet Brown clipart in the bottom right corner. Draw black lines to make pie chart look like a dialogue bubble. Caption the image. :)
(Let me know if you want more detail about any of the steps.)
