The Boston T-Shirt Seller was T-shirt seller on a street corner of Boston. When Gary Heffley came to take his business, he told him he could make him a bundle. After he got the money from his brother Frank, he bought up the person's T-shirts (not knowing that the T-shirts had a typo on them because they had "Botson" written on them instead of "Boston"). When he noticed the problem he went back to the spot where he bought them but the person already left. This caused Gary to stay at his brother, Frank's house.
