The police department in Wyoming, Minnesota tweeted a humorous photo teasing "potheads on 4/20".
The photo shows several bags of chips, video games and a can of Mountain Dew while a cop waits in the background with a net.
The photo was captioned, “Undercover #420 operations are in place. Discreet traps have been set up throughout the city today.”
The department said they enjoy using tongue-in-cheek humor to bring attention to potential issues.
