Go out in public and eat. That's fun as hell watching people stare at you and laugh.

Also though, i clean the house when I'm stoned. Me and my friends got super-high 4/20 and we like made a mess on the kitchen counter like a hundred times and just kept cleaning. Then at like 11 or so, we went into my room and decided to go to sleep. Then my mom came home like 5 minutes later and told us that we were awesome for cleaning the house. That was like the happiest moment of my life.
