Funniest lies you've told your kids

What are the funniest/dumbest lies you've told your kids? I have 2 stepsons, 8 and 5. I absolutely love salt and vinegar chips and snacks. And the younger one always eats all of them. So one time I told him no and right after he asked for some soda and I had told him he didn't need more sugar. So he asked if the chips had sugar and I said yes and he goes "oh I don't need more sugar". So now every time he tries to eat my food he asks if there's sugar and I say no. #horribleparent l
