According to the Daily Mail, the gourd was taken from the front porch of a property in LeDroit Park in Washington DC, which greatly upset young Tommy and made for some mad parents.
To shame the thief, 33-year-old stay-at-home mom Becky wrote a message for him or her on a piece of card and fixed it to the front of the porch.
Becky first posted the note on Facebook but when one of her friends posted it to Reddit her maternal outrage went viral.
The note read: To the person who stole my sons pumpkin. Thank you for the life lesson. This will help teach him that sometimes people are mean for no reason and you just have to brush it off. Because my son is two years old and cannot read this sign, I will add: You are an a******.
