Sam and the Firefly

Gus shows Sam the trick he can do, which is he can make glowing lines in midair using his light.

Sam is amazed and decides to have fun by having Gus follow him directly as he flies.

The hot dog man grabs a net and a jar and runs to Sam and Gus.

He then vows to catch the firefly and take him away (in order to prevent any other dangerous acts by playing another trick on him and his hot dog stand customers again).

He immediately catches Gus in his net, traps him a jar, and puts it into his pickup truck.
