Campaign of disinformation

So I hit Daddy about 10 times yesterday, and there was nothing he could do about it. How do you give some one a timeout when he has to spend all day in a carseat on airplanes anyway? But today when I did it again, he plopped me on the couch with no warning, which surprised and offended me. How to retaliate? I told grandma and mommy "He hit me!" Unfortunately, everyone laughed, because I guess they'd all been there all along and saw the whole incident. Still, there's no saying who they'll believe next time...
