The teacher asked Johnny if he had any pets

The teacher asked Little Johnny if he had any pets.

Little Johnny replied,

“Yes I have a pet cat and this morning before I left for school I put some lighter fuel in the cat’s water bowl. The cat raced up the stairs. jumped over the beds, ran down again, across the living room to the curtains, climbed up to the top and then fell down onto the floor. The cat just lay there motionless.”

“OMG”, exclaimed the teacher, “was your pet cat dead”?

“No” said Little Johnny,

“He just ran out of gas”
