Chris Pratt learned the hard way that if you give a kid an inch, they’ll take a mile.

The Jurassic World actor recently stopped by The Graham Norton Show and revealed that his unique swearing rule completely backfired during a fishing trip with his son, Jack (5).

Pratt began by explaining how the policy originated, saying, “I had this rule with my old man, and I have it with my son, which is: When you’re fishing, you can swear. You can just swear when you’re fishing. It’s just the guys. Go ahead and let loose.”

So when Jack caught a fish and accidentally got poked by its fin, the 5-year-old abided by his dad’s rule and said, “Dad, I’m about to swear. That bass…that bass is stupid.”

Sweet, right? Wrong. The moment took a turn for the worse when Jack told the bass how he really felt and, well, watch the video to see for yourself.

Kids say the darndest things, amirite?
