The story to go with it:
He's a fan of belly inflation. Since he works for a party supply store, he couldn't get his eye off the helium tank. One day, he convince his boss to let him borrow it for the weekend, pretending he had a big party at his house.
He same night, his wish was finally fullfilled. He lay on his bed, put the tube of the tank inside him, and turn the valve.
Almost instantly, he knew this was a bad idea. His belly inflate at a much bigger rate that he expected. Soon enough, his belly grows into a 60 inch balloon, and continue to inflate! The pressure was immense, and his skin was making stretching sounds, gurgles, and a lot for hissing... He can't turn his body now to reach for the valve! He knew he had to wait for the tank to run out helium...
Helium can't make a human fly, even in large quantity. But by the end of his inflation, he feels a little bit lighter. Maybe...*
