Of course

Gary wakes up on his day off thinking about playing with his new toy. He looks around and can't find the ray gun, but he finds the note.

Congrats on finding the Boop Boop Ray Gun bracelet. People with the bracelet can get swaps made between two targets. Side effects may vary depending on subconscious. Side effects might upset conscious mind. Only allowed to use reverse button once per day. Only affects most recent swap. No swap backs after 24 hours. If the ray gun is broken in anyway, the reality will be locked as is. Be careful and have fun.

"That is different...." he mutters and looks at his wrist. A black metal bracelet is attached to his wrist with a red and blue light cycling around it with a single button on side. Gary shrugs and gets ready for hanging out for the day. While eating breakfast he spots his neighbors daughter running outside. She is playing with her now navy blue ball. Gary watches a red line shoot over and hit her. It outlines her pigtails and he watches a blue line hit him. Soon this little girl running around with a balding head. Gary panics and hits the only button on it. The girls hair goes back to normal and Gary calms down. "So its random now. Great." he mutters.
