OKLAHOMA CITY - The line stretches through the store, snaking around the production area, out to the cash registers and out the door, extending down the street.
More than a thousand people lined up outside the Oklahoma Shirt Company Friday afternoon, to fly their true colors -- or at least their colors in the hot new game Pokemon Go.
The Oklahoma Shirt Company jumped on the craze this week, offering players a free screen print of their favorite Pokemon Go team, as long as they bring in their own shirt, sweater or "anything that'll hold still long enough to screen print."
"There's 14 of us that work here and we all play Pokemon Go and we're like, 'this was great, why don't we make some t-shirts for us?'" said Justin Lawrence, who owns the Oklahoma Shirt Company. "We invited our friends, and that's where we messed up. They invited their friends, they invited their friends and then just everybody showed up."
Interest climbed from around 150 people Tuesday - the first day of the promotion - to about 575 Wednesday and 1,500 Thursday.
Lawrence estimates at least 3,000 people came in to the shop for the free screen print Friday -- so many that the store had to turn people away at closing time. The store plans to extend the offer again on Wednesday.
Pokemon Go did provide a platform for some extra t-shirt sales, and a good opportunity for some advertising, but Lawrence said that wasn't the point of the free printing.
"If you love what you do, you don't have to work a day in your life," Lawrence said. "It's really life giving to see all these people in our house. We enjoy our place where we work and so I'm just glad the rest of Oklahoma City can enjoy it with us."
