Wait, whose kid is that?

Party crasher does his stuff in the empty bounce house

The party and people who likely paid for the bounce house Harrison so enjoyed

 "Wait, whose kid is that?  The little one in the orange?", says mother of party guest (who is now enjoying the bounce house after leaving it completely empty for H to take over)

Scene:  Mom, Dad, Kid and Dog take a walk in the neighborhood and wind up in the local park.  Among other activities, the family comes upon a drum circle, makeshift rope swing, AA graduation picnic, cap gun fight and numerous birthday parties.  One party stands out in particular for the completely empty bounce house set away from the celebration..the only way one would know it's connected to a party (and not a free fun gift from the City for park users to enjoy) is the Cars theme of the bounce house matching the myriad Cars theme tablecloths, gift bags and balloons at one of the birthday parties.  

Dad to random person at a picnic table, possibly part of a birthday party : "Do you mind if my son takes a quick jump in the bounce house over there?"

Man at picnic table :  "Sure, at least I'd get my money's worth if someone uses it!"

Dad :  "Cool, thanks."

Harrison proceeds to go insane in his own personal jump house.  Crashing into walls, catching serious air, laughing hysterically, refusing to come out.

In the distance Mom sees a pinata smashing session and hears shouts of joy as the candy hits the ground.  Mom soon realizes these kids are running towards the bounce house Harrison is enjoying.

Mom :  "Hun, don't you think we should grab him so these kids can enjoy their bounce house?  Plus they seem way bigger than H and I don't want him to get a bloody nose or something."

Dad :  "Good call.  Hey, Harrison, come one, let's go see the ducks.  Come on out."

Harrison :  "No.  More jump.  I want more jump.  Harrison jump.  Jump."

About seven kids proceed to jam into the jumper and go almost as nuts as H did initially.  H, the smallest by about a foot and two years, just continues to jump away, laughing, screeching and calling for mom and dad to check out his moves.

Harrison :  "Mommy, Harrison jump.  Daddy jump?  Harrison jump.  Jump, jump."

Mom : "Hun, I think you should just go in there and grab him.  I seriously will flash all of those strangers if I try to crawl in there in such a short skirt.  Just reach in and grab his leg when he comes close to the side."

Random stranger : ""Wait, whose kid is that?  The little one in the orange?"
