Comedian Nathan Fielder made parents across the country Google "rehab" with a little game that he challenged his 39,000 Twitter followers to play.

The fun all started with this tweet encouraging followers to prank their parents:

Experiment: text your parents "got 2 grams for $40" then right after "Sorry ignore that txt. Not for you" Then tweet pic of their response. — nathan fielder (@nathanfielder) April 24, 2013

Sure enough, the responses rolled in quick — and they are hysterical. Here are some of the best parental reactions, which range from enraged to sassy and sweet to totally clueless:
