As much as I hate to say it, I think Lewis was the more enlightened one in this situation.
Also, if you want to post this in the LOTR stream too, you can just:
#1: download the image
#2: go to the meme generator and click "upload your own image"
#3: A tab will pop up saying, "upload from device OR put in image URL". Click on the first option
#4: a tab will pop up and give three options to select from. Click on, "files"
#5: find and select the image
#6: click on, "upload image"
#7: generate the meme, and post it in the LOTR stream
Tell me if anything needs clarification. Have a blessed week!
