Short Story.Name,Author?

Anyone know the origins of this story,read it years ago.I'm pretty sure it was a famous author.

The story goes:in the future we travel vast distances,and have to be put into "hibernation/cryogenically frozen?" to make it to the destination alive.

A mother and son are making a trip and the kid,he's like 10yrs old,thinks it would be fun to hold his breath while they administer the knockout gas(which puts you to sleep for the duration,often 1000 years or more)

Cut to the destination,and they open up the kids chamber and he's laying there with mad grey Einstein like hair,laughing maniacally.

Anyone know it?
