A Montana teen looking to buy marijuana tried to text a drug dealer but hit the wrong number and instead hooked up with the county sheriff.

The message:

“Hey Dawg, do you have a $20 I can buy right now?”

The Independent Record of Helena reports that Sheriff Leo Dutton initially suspected a prank, but quickly realized it was the real deal and messaged back: “How much we talking?”

The sheriff then helped set up a meeting with an undercover drug officer who busted the buyer and a teen-age friend.

The newspaper said the teens “turned white and their knees began to wobble” when the detective showed his badge.

The officers decided not to issue a citation, the newspaper says, but instead got the teens’ parents involved.

“Trying to buy drugs is a crime, but it’s probably worse that they had to face their parents,” Dutton tells the paper.
