Lumpy Rumpy and the Rotten Egg Gas

Lumpy Rumpy, now a high school lad, I'm afraid is still acting very bad, In his school laboratory he did amass, Some stinking, self-made, rotten egg gas. He corked it up in a chemistry vial, Then down the town, he strolled for a while, Choosing a site, the local paper shop, He went in with the vial and took the top off. He hid it behind a large magazine rack, Waiting outside for the putrid gas attack, In three minutes flat the shop emptied out, People holding their noses as they ran about. The fire brigade called, putting masks on, To find the rotten aroma, so very strong, Finally the brigade captain emerged holding the vial, Lumpy grinned to himself, Another prank done with such style.
