I thought of another cute one. My friends and I got into a habit of spelling everything we don't want our little ones to know. I do this with my husband and my mom too. One time I was in the car with my mom, DD5 (4 at the time) ,and DD4 (3 at the time) And I started spelling to my mom the plans of the day. My mom asked me to repeat what I just spelled because she didn't catch it all and my DD5(who was 4) piped up and said Grandma, mom said " we are going to the mall first, having lunch and if the kids are real good after shopping we will get some ice cream"
