Boston Souvenir T-Shirts, are T-shirts sold on a street corner in Boston. Uncle Gary bought some off of a guy, intending to resell them. However, the word was misspelled. Instead of "Boston", it said "Botson" so Gary sold them to Greg's classmates to get money. They also took up the bulk of Uncle Gary's belongings when he moved in with the Heffleys. He sold one to Rodrick, who felt like he got a steal. In the official Third Wheel tour, fans could take shirts of different colors which had "Botson" written on it.
- It's possible that "Botson" was not a typo, and these shirts were promotional items for the Ohio Insurance Company: Botson Insurance Group.
