Two weeks ago, the nightclub DJ and a few buddies were sitting at a sports bar in Denver, joking about how funny it would be if the Seattle Seahawks and Denver Broncos — the NFL teams from the two states that have legalized marijuana — made it to the big game.

They decided to plunk down a $44 wager — the fee for registering the Internet domain http://www.stonerbowl.org — just before the Seahawks and Broncos won their conference championships.

It paid off. They’re now using the site to hawk T-shirts and hats celebrating the coincidence. One shirt features the Vince Lombardi Trophy, reserved for the game’s victors, refashioned into a bong. Another features a spoof of the league’s logo, with the letters “THC” — for marijuana’s active compound — replacing “NFL.”
