“Must Lett Tom Pick Onion” (mustard, lettuce, tomatoes, pickles, onions)

“Must Lett Tom Pick Onion” are sandwich instructions to add “mustard, lettuce, tomatoes, pickles, onions.” It’s not a sentence, but this was posted on Reddit—Funny on October 9, 2015:
   
“I spent 5 minutes trying to figure out who Tom is, and what his onion picking skills have to do with my sandwich.”
 
The sandwich joke has been printed on several images.

When the list reads… Must, let, tom, pick, onion… Don’t waste time trying to figure out who Tom is, and what his onion-picking skills have to do with the sandwich.
