No, you can't....

...grind up crayons with my can opener.
...throw your sucker stick behind the couch.
...launch that huge boulder off the deck.
...cut up styrofoam into minuscule pieces with my butcher knife and spread it all over the backyard.
...put a stick of gum on the griddle while I'm cooking pancakes.
...sit in the wagon and ride down the hill and into the street.
...walk through my house with mud-caked shoes.
...attack my brand new black bar stools with sand paper, just to see what happens.
...put chewed gum in your shirt pocket.
...spray perfume in your sisters face.
...wipe boogers on the wall next to your bed.

A certain child of mine did not ask permission to do all of the above; he just did them. His imagination and curiosity have no limits and I love him for it!
